My biggest regret is not doing Boogie Nights ,” DiCaprio tells director Paul Thomas Anderson in Esquire’s latest cover story. The actor turned down Anderson’s 1997 porn-star drama after starring in The Basketball Diaries because it conflicted with his role in James Cameron’s Titanic.

DiCaprio, who is starring in Anderson’s upcoming action thriller “One Battle After Another,” told the director that he “rarely” watches his own films, but he’s seen “The Aviator” the most.

Leonardo DiCaprio said his 'biggest regret' in his career was turning down Mark Wahlberg's role in 'Boogie Nights,' which he called 'a masterpiece'
