Leonardo DiCaprio regrets turning down Paul Thomas Anderson`s 1997 film `Boogie Nights` nearly three decades ago.

According to Variety, DiCaprio was the first choice to play the lead character of Eddie Adams, which eventually went to Mark Wahlberg. DiCaprio had already committed his dates to `Titanic,` which prompted him to refuse Anderson`s offer.

In a recent interview, the `Inception` star said, "My biggest regret is not doing `Boogie Nights.` It was a profound movie of my generation. I can`t imagine anyone but Mark in it. When I finally got to see that movie, I just thought it was a masterpiece. It`s ironic that you`re the person (Anderson) asking that question about regrets, but it`s true," as quoted by Variety.
