Raoul Duke In Fear and Loathing in Las Vegas: Fear and Loathing in Las Vegas is not everyone’s cup of tea. The film is complex and can easily bore the audience if they are not into films that deal with drugs and hallucinations and basically any adventure that is illegal. Johnny Depp played Raoul Duke, a man who during his trip to Las Vegas consumes drugs more than he can handle and literally ends up having the ‘trip’ of his life.
