Casting alert: Michael Shannon in 'Premium Rush'

Oscar-nominated actor Michael Shannon, who briefly shows up in the disastrous "Jonah Hex," is boarding "Premium Rush," a thriller starring Joseph Gordon-Levitt. Jamie Chung is also part of the flick.

Written by David Koepp, who is also directing, the film follows a bike messenger who gets chansed by a ruthless cop because he's transporting a mysterious envelope. Shannon would play the cop, of course.

The Hollywood Reporter says Chung would be playing Gordon-Levitt's ex. John Kamps co-wrote the script. Shannon scored an Oscar nomination for his awesome performance in "Revolutionary Road.
