"The Mind of Mr. Soames" is an interesting vehicle for Terence Stamp, who's otherwise known for much more brutish characters. But the film's premise (sympathetic innocent with unusual traits is cruelly confined for scientific observation, but eventually seeks freedom) is overly familiar now, whether we're talking about "E.T.," "Powder," "Escape from the Planet of the Apes" or countless other sci-fi melodramas. Soames (Stamp) is a man who has been in a coma for 30 years, but is miraculously awakened with a new medical procedure. Intense therapy teaches him to belatedly talk, walk and reason, but his host facility is reluctant to release him once he seems capable of sustaining himself. Of course, there's one good-hearted doctor (Robert Vaughn) who understands. A weak ending leaves a bland aftertaste.
