While you may be tempted to pass up "Criminal" because of its ridiculously high concept -- something about mind-swapping and the CIA --  the thriller boasts an impressive cast that calls out for a second look: Ryan Reynolds, Kevin Costner, Gary Oldman, Tommy Lee Jones, Alice Eve, Gal Gadot and Michael Pitt.

See?

This first trailer pretty succinctly lays out the film's premise: In a last-ditch effort to stop a diabolical plot, the memories, secrets and skills of a dead CIA operative (Reynolds) are implanted into an unpredictable and dangerous death-row inmate (Costner) in the hopes he will complete the agent's mission. There's a bit of a "Ghost" vibe to the trailer, with a stinger about redemption or something, but ... hey, that cast!

Directed by Ariel Vroman ("The Iceman"), "Criminal" opens April 15.
