Morgan Freeman, Robert De Niro, Michael Douglas and Kevin Kline. Hard to imagine that group of actors have never appeared with one another in movies before. But that's about to change, with the release of "Last Vegas," and TODAY's Matt Lauer visited the guys on the movie's set to get some inside scoop.
"It was a shock that neither one of us had ever worked with anybody else before," noted Douglas. "And in that first week, you're like, 'Man, I hope this works.' Because all you need is one bad apple in the group.... I think we were pleasantly surprised."
Of course, one bad apple might not have been a bad thing -- because some of the behavior in "Last Vegas" is pretty bad; as Matt Lauer noted, the film has shades of "The Hangover."
"It's an alter kaker 'Hangover,'" joked Douglas, using a bit of Yiddish off-color slang. (Look it up.) And all four of this film's stars qualify for that designation, they agreed.
"Last time we looked, yeah," said Freeman.
So is the film really raunchy? "It's getting raunchier as we go along," laughed Douglas. "The language has gotten ... a little fuller and fuller."
"That's no way to put it, Michael. Fuller and fuller?" wondered Freeman.
Well, let's just say there's a big party, a funeral and a Madonna impersonator, among many other things. After all, what happens in "Last Vegas" stays in Las Vegas.
And in the end, everybody worked out just fine. "Everybody's at ease about their own -- everybody else's process and rhythm," said De Niro. "Everybody does what they want. Everybody adjusts to everybody. We're having a lot of fun."
But you'll have to wait to see how it all turns out: "Last Vegas" won't open in theaters until Dec. 20 -- of 2013.
