When Marky Mark decided to make the leap from pop star to serious actor in the mid-1990s, his first major role was in The Basketball Diaries.  Nearly two decades later, Wahlberg (né -y Mark) will guide his 2011 equivalent through a similar path.  Deadline reports Wahlberg and Justin Bieber are in negotiations with Paramount to star in an untitled drama set in the world of street basketball.  The idea surfaced over NBA All-Star weekend, when Bieber impressed Wahlberg and producer Stephen Levinson with his skills in the celebrity game (Bieber was named MVP).  Ian Edelman, creator of the Wahlberg/Levinson production How to Make It in America, will write the script, described as “The Color of Money meets The Karate Kid.”  More after the jump.
