BURBANK, CALIFORNIA, UNITED STATES (MARCH 3, 2008) (REUTERS - Actor Jack Nicholson is on board with an internet ad supporting Hillary Clinton that features memorable clips from his films. The campaign commercial features famous scenes from movies like "Chinatown," "A Few Good Men," and "The Shining" to praise various aspects of the Clinton platform and advocate her fitness to lead the country at a time of war. Nicholson's on-screen dialogue is interspersed with black slates with messages promoting Clinton as the candidate of choice.

The ad was created by Clinton supporters in Hollywood and approved by Nicholson. The Oscar-winning actor appears in the last clip saying "I'm Jack Nicholson, and I approve this message." The Barack Obama camp responded by producing a parody of the ad that also uses Nicholson movie clips. This one ends with Nicholson swearing, ranting and throwing dishes. "Sorry Jack. Vote Obama," that video concludes.

Both commercials have been posted on the popular video site "You Tube" in recent days. And, according to "You Tube" statistics, the Clinton ad has received more than 1.2 million hits so far.

When asked about the effectiveness of celebrity endorsements, Hollywood film studio employee Heather Duncan told Reuters she had already made up her mind about which U.S. presidential candidate to support. But she said she believed those who are still trying to decide between Clinton and Obama may be influenced by the ad.

"If I didn't know a lot, it would probably make me more interested in finding out more," smiled Duncan. "I think, seeing someone that I like watching on television or in movies give their opinion, then I'd be curious maybe I'd go look at a website or try to find out more information."

Television marketing executive Michael Valle disagreed.

"I'm not exactly sure why I should care what a celebrity has to say about politics," said Valle. "Especially since their job is to entertain, not to inform. So, their opinions really don't have much weight as far as my decisions go as far as, uh, politics in general. Or life in general I would say."

Still, the effectiveness of a popular website like "You Tube" is not lost on many.

"Just about anybody today has access to 'You Tube' and, um, word of mouth would spread it," shared university student Rondi Bryson. "Anything, whether someone's political or not, I think because of controversy want just to see what it's about. And I think it would, you know, them watching it would subliminally spark an interest or kind of open up something in them that that might make them want to make a choice to get involved or not to get involved."

Los Angeles resident Robbie Dodd echoed the sentiment and reminisced about how seeing a particular presidential hopeful on a cable television channel aimed at a youthful demographic impacted his decision at the polls years ago.

"Yeah, well, I mean, it's obviously proven to be very powerful. 'You Tube', I mean, hosted one of the debates and everything," laughed Dodd. "Um, it, it's good. I remember being young and seeing Bill Clinton being on MTV and I voted for him, because of that. So, yeah, it probably does have more of an effect for younger kids and everything. Hey, younger kids seem to be responding more to Obama. So, we'll see what happens."

Duncan says she is voting for Clinton, but expressed frustration that the U.S. Senator is not sweeping the primaries and caucuses.

"I'm definitely a Hillary supporter, and I'm really surprised that she's not, like, winning, like, hands down, because she's like really experienced. And I feel like younger voters are voting for Obama without any sort of substance to it. Like they're just picking him because he's the cool candidate."

And, Bryson underscored the impact a star-studded promotion may have on voters looking for a cue about what to do when they cast their ballot.

"I like Jack Nicholson, you know, I don't really know Hillary or Obama, but um, it would definitely make me listen to what he has to say, and maybe make a choice from then."

"There is nothing on this earth sexier, believe me gentlemen, than a woman you have to salute in the morning," Nicholson says in a clip from the 1992 military drama "A Few Good Men."

In another, "Hubba hubba hubba, money, money money, who do you trust?" Nicholson asks in his role as the Joker from 1989's "Batman."

Clinton and Obama face a round of state primaries in Texas, Ohio, Vermont and Rhode Island on Tuesday (March 4) that could decide who faces Republican John McCain in the November presidential election.
