Face/Off (1997)

Castor Troy begins in Nicolas Cage's body and later occupies John Travolta's, so the scene-stealing villain belongs to both performances. Cage supplies an extravagant appetite that Travolta then translates into a different physical vocabulary. Sean Archer's duty and family grief give the hero a clear line; Troy's pleasure in exploiting a respectable identity makes every social encounter unstable. The face exchange is the premise, but the actors borrowing each other's excesses are the real attraction.
