With Tom Cruise now too aged to convincingly play a young law school grad and Shia LaBeouf not famous anymore, the onus of starring in John Grisham legal thrillers falls to Zac Efron. The hobo punching bag and Neighbors star has signed on to an adaptation of Grisham's The Associate, in which he'll play a young law graduate blackmailed into spying on high-profile cases at a large law firm. These spying duties will include alternately sneaking around, running full speed through the hallways, and frantically pressing elevator buttons. (THR)
