Martin Scorcese’s GoodFellas is in the Mt. Rushmore of mob movies, along with The Godfather, Casino, The Departed, and others. Based on real-life mobster Henry Hill, the film chronicles the implosion of a mob family in intimate detail. With career-defining performances by Ray Liotta and Joe Pesci, alongside acting greats Robert De Niro, Lorraine Bracco, and Paul Sorvino, the movie is an American classic. GQ interviews over 60 members of the cast and crew for a look back on the film’s 20th anniversary.
