In an interview with James Lipton on Inside the Actors Studio, John Travolta went into details of the many obstacles of tackling his role as Vincent Vega. The most challenging being that of how he was going to show the essence of his character as that of a heroin addict. Never using the drug himself, director Quentin Tarantino had Travolta research his characters addiction by speaking to a recovering heroin addict that he (Quentin) knew personally. Travolta asked Tarantino’s friend to tell him how could he know what it felt like to be on heroin (without actually using it of course). Tarantino’s friend explained “If you want to get the ‘bottom envelope’ feeling of that, get plastered on Tequila, and lie down in a hot pool. Then you will have barely touched the feeling of what it might be like to be on heroin.” John Travolta then explained that he was ecstatic to tell his wife that he was “told” in order to research aspects of his upcoming roles’ character, he had to get plastered on Tequila and lie in a hot pool. He stated she happily joined him at the hotel hot tub which had shots of Tequila lined from end to end on the railings to assist him in his “research”.
