Mark Wahlberg will play the drug kingpin Jon Roberts in the remake of the 2006 documentary Cocaine Cowboys, which chronicles the story of the largest cocaine trafficker in Miami in the 1970s and 1980s, and he's persuaded Leonardo DiCaprio to play the supporting role.

The untitled flick "will blow Blow out of the water," says a movie insider who added that Leo "is excited about the opportunity to play the airplane pilot who travels with Mark's character to obtain kilos of cocaine from Pablo Escobar."

This will be the third film that the pair has been in together. Mark, 36, and Leo, 33, starred in 1995's The Basketball Diaries and most recently in 2006's The Departed.
