"I'm an actor, and this was a story that I found compelling and I felt there was something to contribute to it," he explained.
The "new" Cruise has been working overtime to keep a low profile. He no longer wishes to speak out about Scientology.
"Now, I just say look, I'm not going to talk about my religion, and if people want to know about Scientology, they can absolutely just go to the Web site."
This year, one of the most famous people in comedy just happened to look like one of the most famous people in politics. In August, "30 Rock" star Tina Fey struck gold when Sarah Palin became a vice presidential candidate.
Fey bears only a slight resemblance to Palin, but this, combined with her impersonation of Palin's mannerisms, dress and speech patterns resulted in a whole that was greater than the sum of its parts. Watch Fey impersonating Palin HERE.
"It's a strange, perfect storm of, I looked just enough like her, and the wigs were good," Fey told Barbara Walters. "A lot of it is luck."
Fey grew up a self-described nerd in a suburb of Philadelphia. She started doing improv at Chicago's Second City, a troupe that has launched many careers on "Saturday Night Live," including her own.
In 1997, Fey landed a writing position at "SNL" and quickly became the show's first female head writer. She went on to write and act in the successful 2004 film "Mean Girls" alongside Lindsay Lohan. And two years ago created her own NBC comedy series, "30 Rock," where she functions as a triple threat: writer, producer and star.
This year has been a busy one for Fey, 38, who also starred in the hit movie "Baby Mama," while at the same time finding time for her 3-year-old daughter and logging 12-hour days on the "30 Rock" set.
But all of this was eclipsed when she portrayed Sarah Palin on "Saturday Night Live."
"The first thing I noticed about her was that she had this very full-of-pride way that she would say 'Alaska,'" Fey said. "Every time she would talk about 'Alaska,' she would just, she really, you can tell that she genuinely loves Alaska."
Fey's big smile during the Palin sketch was a detail she added after observing Palin's body language during interviews, and finding that "She would talk through a smile sometimes, if she was trying to 'zing' somebody, talk about Joe Biden or something like that. The tougher the thing she was saying about the campaign, the bigger the smile was."
Some, especially right-wing bloggers, criticized Fey's impersonation, in particular her spoof of Palin's interview with CBS "Evening News" anchor Katie Couric.
"I never did feel that we were mean to her," Fey said. "I feel that we stuck to, a lot of times, things that she herself had said."
"There's a very strange double standard, because it's a woman, portraying another woman," Fey said. "The jokes we used to do about George W. Bush were that he was an idiot. No one ever would stop and say, 'Oh, that seems kind of mean.'"
From action films to science fiction to romantic comedies, no one has ever created a string of movie blockbusters quite like Will Smith.
And, when it comes to the box office, Smith is Hollywood's most bankable star. Each of his last eight movies grossed more than $100 million and his films to date have pulled in more than $5 billion worldwide.
