For all the action and special effects you can stuff into a film, one of the most appealing things to an audience can be seeing two of their favorite stars face off for the first time. Think Pacino & De Niro in "Heat." Diesel and The Rock in "Fast Five." Crystal and Williams in "Father's Day." Ok, maybe not the last one. As such, there's one film that, ever since its announcement, looks to be the true successor to that coffee shop scene in Michael Mann's classic, a team-up so enticing that it can only be a license to print money. Wahlberg. Bieber. Boom. Two tickets and a large popcorn, please.  Yes, the former teen heartthrob Mark Wahlberg, and current teen heartthrob Justin Bieber, have, since April, been planning a collaboration, a drama from "How To Make It In America" creator Ian Edelman that takes place in the gritty world of street basketball.
