Dr. Jack Hammond (Dudley Moore) is a noted heart surgeon whose personality is switched with his teenage son Chris (Kirk Cameron) in this uninspired comedy. The ingestion of a brain transference serum is the catalyst for the comic catastrophe and the confusion that follows. Sean Astin and Patrick O'Neal co-star with Margaret Colin and Catherine Hicks. A decent idea for a comedy that has since been done better in Brian Gilbert's 1988 comedy Vice Versa starring Fred Savage and Judge Reinhold.
