With his comedy tour a hot ticket and his “Frank TV” series taping its second season — having outperformed expectations at TBS on its initial limited run — comic impressionist Frank Caliendo (right) is feeling on top these days.  He’s also feeling relieved to be away from the mean antics often seen on his former place of funny business, Fox’s sketch comedy show “MADtv.’”

“When I was at ‘MADtv,’ we would attack a lot.  That’s the reason why nobody wanted to do ‘MADtv,’” he claims.  ”They ripped on people for no reason.  They were outing Rosie O’Donnell ahead of time.  Why, if you are a big actor or actress, would you want to be on a show that’s being mean to people?” asks Caliendo, who says he often avoided going too far.  ”I wouldn’t do a lot of stuff they asked me.  I would just tell them I didn’t feel comfortable with certain things.”

As for his own sketch comedy show, returning this fall, Caliendo says they’re just trying to have fun and have no intention of hurting anyone.  ”We try to take the smart route.  We’re not doing attack pieces.”

In fact, Caliendo, who’s most known for his dead ringer impersonations of George W. Bush and John Madden, says he has no ill will towards the people he imitates.  ”I like most of the people I do impersonations of, although John Madden hates me.”

THE VIDEOLAND VIEW: “Entourage” creator/writer/exec producer Doug Ellin has reported he has four more seasons of storylines already in reserve for the Emmy-winning HBO show – but is the cast locked down?

“We’re not signed for it, but we want to do it,” declares Kevin Connolly, who co-stars in the show based on actor/exec producer Mark Wahlberg’s showbiz experiences with Adrian Grenier, Kevin Dillon and Jerry Ferrarra.

“I’ll tell you.  I swear to God if you stick that paper in front me I will sign on the dotted line for 50 seasons! Anything to make it not go away. I think anybody that wouldn’t would have to have their head examined. The worst thing about this show is that some day it will come to an end. It’s going to be like the worst day of my life.”

Connolly (right) says the troupe — which is half way through shooting the fifth season of the show that returns in September – “just shot an episode in The Joshua Tree Monument in the desert. Our first episode was in Hawaii and we’re going to do a New York episode and that’s just three out of 12.  So just for the locations alone… And one of the other benefits of being on an HBO show, is the time commitment is really small. We shoot four months out of the year… It’s so ideal.” Not to mention the plethora of hot babes encountered by this entourage weekly.  Rough job!

He adds, “Ultimately we’d like to do eight years of the show. That would be where everybody would feel like ‘We did it’ you know, because we’re not like a network. Eight years for us is just about 100 episodes” — enough needed for syndication – “and that’s five years on a regular network.”

IDOL THOUGHTS: Teenage actress Meaghan Jette Martin figures that once “Camp Rock” debuts tonight (6/20), “Everybody’s going to hate me.  It’s sad, but it’s okay,” laughs the vivacious blond, who portrays the junior diva/rich daughter of a rock star  – and nemesis of Demi Lovato’s character – in the highly-anticipated Disney Channel original movie starring the Jonas Brothers.  “She’s really mean, pretty terrible.  Her mom is very neglectful so you learn throughout the movie why she’s mean.”

Martin is also the object of tween envy, of course, having worked in close proximity to the It Boys of the pop music scene.   As for her take on the Jo Bros.?  “They definitely are very different from each other.  Joe is the crazy, hilarious one as everybody knows.  He’s not shy about letting people know that. He’s so much fun to be around. You can be incredibly down and so sad and the minute Joe’s’ around, he will make you happy.

“Nick is always there to comfort you, but he’s more the serious one, he’s very sensitive and the funny thing is whenever he has too much caffeine or sugar, he won’t stop talking.  It’s really cute.

“Then Kevin is like such a gentleman.  Every night he would walk each and every one of us to our home room when we were filming ‘Camp Rock,’” she says of herself and her other femme cast mates, “’cause he wanted to make sure we were safe. They’re really great guys. And none of us are making it up, they really are great guys.”

THE BIG SCREEN SCENE: Clint Eastwood is deep into casting of “Gran Torino,” the drama that director Clint got movie star Clint out of retirement to make.  You may recall Eastwood’s statements that he couldn’t imagine going out on a better note than with “Million Dollar Baby,” and how he turned down Paul Haggis, who was interested in Clint’s acting services for “In the Valley of Elah.”

Anyway, the new film starts shooting next month in Michigan.  Among the subsidiary characters still to be cast is Clint’s son.  The feature has the 78-year-old legend playing a bitter old man, a Korean War vet, who can’t get along with his children or neighbors – but becomes the friend and protector of a Hmong family in his neighborhood.  His prized 1973 car gives the film its title.

Chris O’Donnell, who has a role in Mark Wahlberg’s fall-debuting “Max Payne” feature, scoffs word that the filmmakers are trying to get a PG 13 rating for the adaptation of the violent, hugely popular video game.

“Good luck.  I’ve been doing my ADR (post-production audio recording) and seeing the footage, it’s just not appropriate for kids on too many levels.  For adults, yes.  Very entertaining.  I’m a big fan of Mark Wahlberg.”

O’Donnell has strong views about what is and is not okay for children these days.  That’s not surprising, considering that the actor, who rose to fame with films including “Batman Forever” and “Scent of a Woman,” has five offspring of his own – three boys, two girls, ranging from eight years to six months old.

“At home, I hear ‘Dad!’ about a hundred times a day.  That’s what it’s all about for me,” says Chris, who’s been married to Caroline Fentress since 1997.

He complains that he’s “seen most of the kids’ films that are out there now, and a lot of films that say they’re PG are really not appropriate for children.’”

That’s not the case, he points out, with his latest movie, “Kit Kittredge: An American Girl’s Story,” opening in limited release Friday (6/20) – widening July 2.  In it, he plays papa to the title character portrayed by Abigail Breslin.  Also starring Julia Ormand, Joan Cusack and Stanley Tucci, the movie is set during the Great Depression of the 1930s, complete with home foreclosures and soup kitchens.  O’Donnell’s character loses his car dealership.

“You want to protect your kids from the harsh realities of life, but there come times when those realities intervene,” he notes.

O’Donnell tells us there’s a film shooting in Boston this summer that might be in his future, but “I’m hoping to stay closer to home – maybe do a cable series.  I like the fact that they do fewer episodes than network shows.  The pace is more of what I’m used to than ‘Grey’s Anatomy’ was.  On one-hour shows, the pace is overwhelming.”

MEANWHILE: Abigail Breslin is looking forward to some down time now that “Kit Kittredge” is almost launched — on the heels of her “Nim’s Island,” on the heels of “Definitely, Maybe.”  The busy 12-year-old 2006 Oscar nominee (“Little Miss Sunshine”) also has “My Sister’s Keeper” with Cameron Diaz in the can.  She tells us that now, “I’m just going to hang out at home and have sleepovers and stuff like that.  And my family’s going to Prince Edward Island” for vacation.  Still, she has her sites set on what’s next.  “I would like to play Helen Keller or Lady Jane Gray.  I just read a book about her, and she was the Queen of England for nine days.  I just thought that was really interesting.”

THE VIDEOLAND VIEW: Jamie Lynn Spears has brought teen pregnancy to the forefront this year, which makes the new ABC Family drama “Secret Life of the American Teenager” all the more relevant.  ”You deal with teen pregnancy and a lot of time people try to avoid talking about stuff like that, but it’s true to society,” notes newcomer Daren Kagasoff, who is starring alongside veteran actors Molly Ringwald, John Schneider and Ernie Hudson in the show that deals with an unexpected teen pregnancy.  ”Like with Jamie Lynn Spears, things happen and you deal with them in whatever way is morally correct in your mind.  Our show keeps you updated with what’s going on in real life and how some people choose to handle these situations.”

The show, premiering July 1, is Brenda Hampton’s latest project after her long run with the other show she created “7th Heaven.”

While Kagasoff wasn’t the studio’s first choice to be one of the main teens, he tells us he couldn’t believe how much Hampton fought for him.  ”They weren’t sure about me because I had no prior experience acting in front of the camera.  They wanted to audition other people with more experience, but I guess nobody really caught their eye so Brenda Hampton pushed for me. She came to my house with a dozen roses to tell me I got the part.  It’s a moment I’ll never forget.”

BIGGER SCENE: When “Law & Order: SVU” producer Neal Baer finds himself with any free time from the show, he turns to “my other side of my life, doing photographic projects with www.joinipe.org – the Institute for Photographic Empowerment.  The idea is to give cameras to people who are traditionally disenfranchised and give them a chance to tell their own stories.”  The endeavor has brought forth video from young people in several far-flung locales, including “AIDS orphans in Mozambique and South Africa,” according to Baer.  It’s also, he says, led to a forthcoming book and documentary that Baer reports “We’re cutting right now.”
