Oscar winner Leonardo DiCaprio admits to director Paul Thomas Anderson that not starring in "Boogie Nights" remains his greatest Hollywood regret.

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. “That’s simply because it was such a special moment to me,” he said of starring in the Howard Hughes biopic.
