At the time, Anderson was a 27-year-old wunderkind. New Line Cinema/ Courtesy: Everett Collection "I'll say it even though you're here: My biggest regret is not doing Boogie Nights," the actor confirmed. "It was a profound movie of my generation. I can't imagine anyone but Mark [Wahlberg] in it. When I finally got to see that movie, I just thought it was a masterpiece. New Line Cinema / courtesy Everett Collection "It's ironic that you're the person asking that question," he told Anderson, "but it's true."

It follows a former revolutionary, now past his prime, embarking on a wild quest to find his missing daughter. View this video on YouTube Warner Bros. Pictures / Via youtube.com "Why did it take us so long?" Anderson asked DiCaprio about finally working together. Frazer Harrison / Getty Images Anderson certainly wanted DiCaprio for Boogie Nights, which painted a bleak portrait of the porn industry's rise in California, but was famously turned down - as DiCaprio already had a prior commitment at the time to star in a film called Titanic. 20th Century Fox Film Corp.

Kevin Mazur / Getty Images Anderson did just that, practically transforming the former model and rapper into a respected actor. The role of Dirk Diggler indeed demanded a lot of the lead actor, including scenes of emotional desperation, drug-fueled paranoia and a whole lot of nudity.

He first revealed turning it down during a 2008 GQ interview with Titanic director James Cameron, who cheekily asked DiCaprio if he would make a different choice "if you could go back." Frank Trapper / Getty Images "I'm not saying I would have," DiCaprio replied at the time. "But it would have been a different direction, career-wise. I think they're both great and wish I could have done them both." Cbs Photo Archive / Getty Images This article originally appeared on HuffPost.
