What do you get when Michael Douglas, Robert De Niro, Morgan Freeman and Kevin Kline journey to Las Vegas in a movie? If this were a few decades ago, they'd probably all double cross and kill each other. But today? They get to play old buddies having one last hurrah in a similar fashion to 'The Hangover.' Because the only thing funner than old, drunk people are old, drunk movie stars. Or at least that's what everyone involved with 'Last Vegas' thinks.
