The legendary actor, along with Morgan Freeman, Kevin Kline and Michael Douglas, took some very popular pop songs heard on the radio every day, and gave a dramatic reading of the lyrics during their film's junket interview with Screen Junkies.
Along with Miley Cyrus' "Wrecking Ball" (which is actually a pretty intense song), Ylvis' "The Fox (What Does the Fox Say)", One Direction's "Best Song Ever" and Alison Gold's "Chinese Food" are also interpreted.
De Niro and Douglas whizzed through their readings, while Freeman became extremely perplexed by "The Fox" (understandable) and Kline seemed to really become one with "Best Song Ever."
The four actors star in Last Vegas, a movie that has a similar feel to Hangover, except the guys are a little older.
Billy, Paddy, Archie and Sam are a close-knit group who have been good friends since childhood, and when Billy decides to finally let go of his bachelor card, the group of guys head to Las Vegas for one last hurrah. But Sin City is different from what they remember, and that ends up causing some problems.
