I really don't know why he's taken to chatting with me. Honestly I don't. As a co-worker has pointed out to me, there are few people who share less in common with Jack Nicholson than I. And yet for the second time in four months I spent an hour on the phone last night chatting with perhaps the most famous actor in the world.

Last night we chatted mostly about politics (in November it was "Chinatown" and "Batman" respectively in a two-part chat). Surely you've seen his campaign ad for Hillary Clinton by now. So it was me at my desk in mid-town Manhattan, posters of "The Last Mimzy" and "Bratz" hanging over me, and Jack was where? I'm guessing his feet were up. He was in plush robe of some sort. Maybe he was sipping some whiskey. Neat of course. Bob Evans was probably in a cabana out back. Me, I had a box of Krusty O's next to me. Read more...

Alright, I'll admit it...when I first started watching this supposed "Nicholson for Hillary Clinton" ad I assumed it was the work of a modestly talented mash-up artist. And it still might be. But then where and why and how did that Nicholson testimonial come from at the end of the video? So many questions...and will any of it matter in another 48 hours when Hillary's fortunes may look as murky as the Joker's did after he danced with the devil in the pale moonlight? Well, in the meantime, enjoy. (Update: Jack Nicholson responds exclusively to MTV News - Click here to read!)

Nearly twenty years may have gone by but Tim Burton still feels a debt to one man for the success that was "Batman." "Jack [Nicholson] was so good to me. He really helped me through 'Batman' completely. I was just a kid. Everybody was wondering how I got this job and he was just quietly supporting me. I'll never forget that," the visionary director recalled when I brought up the famed franchise.

When I told Burton that Nicholson had seemed almost upset about Heath Ledger taking over as the Joker in the upcoming film, the director laughed it off saying, "That's what's great about him. He could be not serious but he also could be serious. That's what gives him an amazing quality as an actor and a person."

But just because it's laughs all around when it comes to Burton and Nicholson doesn't mean the "Sweeney Todd" director doesn't harbor some resentment over how his "Batman" films were treated. Read more...

When I spoke with Jack Nicholson a few weeks back the conversation at one point veered into the latest generation of talented thespians. When asked about this new crop of actors, I expected Jack to cite the work of a Leonardo DiCaprio perhaps but what I got instead was something altogether surprising.

"I've been watching a TV show called 'Mad Men' [that has] an actress on it that I had cast in 'Anger Management,' January Jones," Nicholson said. "I think she's very talented." Alright, fine. I'm into "Mad Men" too, but no, Jack was just getting started: "I've been watching this series on TIVO, right? I didn't read the credits. I didn't know it was her! When I saw the name I said 'are you kidding me'?!?" Read more...

"Wait 'til they get a load of me," Jack Nicholson cackled maniacally nearly 20 years ago in Tim Burton's "Batman." Well come next summer, we'll get a load of a whole new interpretation of the Joker when Heath Ledger grins from ear to ear in "The Dark Knight" and guess what, Jack is not happy.

"I'm furious," Nicholson whispered to me last week when I asked him point blank how he felt about Ledger assuming the role. (Check out my full extensive conversation with Jack Nicholson here and find out about the unrealized second sequel to "Chinatown" in part one of the Nicholson interview here.)

Clearly the passage of time hasn't mellowed Jack one bit when it comes to the Joker. His voice rose as he said, "They never asked me about a sequel with the Joker. I know how to do that! Nobody ever asked me." For Nicholson the part of the Joker was an important one. "The Joker comes from my childhood," he explained. "That's how I got involved with it in the first place. It's a part I always thought I should play."

Saying that Warner Bros. "kind of drove the franchise into the ground," Nicholson added that he wasn't inclined to go see "The Dark Knight." He went on to praise filmmaker Tim Burton to no end. "[He's] a genius. He had the right take on it. That's why I did the movie. [Burton is] one of the great moviemakers. I think the world of him."

Are you with Jack or Heath? Who is the ultimate Joker? Should Christopher Nolan and company have considered bringing Jack back? Here's your bat signal to weigh in below!

His partner may have implored him, "Forget it Jake, it's Chinatown," but Jack Nicholson is not quite willing to forget Jake Gittes and his dark and mysterious Los Angeles adventures. It's been 17 years since Nicholson last assumed the Gittes moniker, but with the release of "Chinatown" and its sequel "The Two Jakes" on DVD, don't look now but Jack's got a third installment on the brain.

In a rare interview last week, Nicholson revealed exclusively to MTV News the grand initial vision for a "Chinatown" trilogy that he and writer Robert Towne hatched. Says the legendary actor, "We always planned on making three films. We wanted it all to be tied into elemental things. 'Chinatown' is obviously water. 'The Two Jakes' is fire and energy. And the third film was meant to be about Gittes' divorce and relate to air." Read more...

Sure, we get to talk to some pretty amazing people here. But there's something a little bit different about Jack Nicholson. The man just doesn't talk to the press. Just ask James Lipton. He's been begging Big Jack to be on his show for years. So when I learned not so long ago that Nicholson had consented to my request to talk, you'll forgive me if I was a bit taken aback. I've interviewed John Travolta. Just recently I re-enacted a scene from "Rocky IV" with Apollo Creed himself. But Nicholson?!?

The first thing Jack did when our chat began was to ask me to remind him of my name. "This way I'll know it for at least a few minutes," he said in tandem with the most famous chuckle perhaps in the world. And we were off to the races. Check out my extensive conversation with Jack Nicholson right here.

In the green room, Nelly's "Hot In Herre" is playing while Robin Williams — wearing a kilt — yells out "Pole dance!" Thankfully, he didn't do one. Later, he and Bruce Willis are posing for pictures — Williams says (in a thick Scottish accent) "Last year we went to see 'The Queen' but the only person who came out was Helen Mirren." ...

Jack Nicholson is the man. He talks to Cameron Diaz for several minutes before they're joined by Adam Sandler and then Williams — and then Michael Chiklis. Nicholson tells him he didn't want to overdress for the night and appreciated that Chiklis wore a T-shirt.
