YouTube video inspired Leonardo DiCaprio's 'Wolf of Wall Street' scene

Leonardo DiCaprio has confessed that a YouTube video called Drunkest Guy Ever Goes for More Beer inspired him for his performance in Martin Scorsese's film The Wolf of Wall Street.

The Titanic star said at the Santa Barbara International Film Festival that the comic scene where his character, Jordan Belfort, tries to get to his car while on Quaaludes, was inspired by the funny video, People Magazine reported.

The 39-year-old actor added that he "obsessively" watched the video to help him capture the physicality of someone under the influence of a sedative-hypnotic drug.
