He's not the first actor to impersonate a president... but he may be the last.

Moon Over Parador

Underappreciated actor Jack Noah is on location in Parador at the time the dictator dies. The dictator's right-hand man makes Jack an offer he cannot refuse... to play the dictator. Jack's acting skills fool the masses but not close friends and employees of the dictator.
