Dirk Bogarde can be described as a great actor who was never in a classic film. Popular films, like the Doctor series, certainly; good films like The Tale of Two Cities; excellent films like The Servant; fascinating, discussed films like Death in Venice and The Night Porter. But classic films like Casablanca - maybe Darling comes closest, and that's not even his movie.
"The Mind Benders" is another Bogarde film on the bizarre side. When an elderly scientist is suspected of treason, an investigator endeavors to find out whether his experiments in isolation made him do something - betray his government - that he ordinarily wouldn't have done. One of his coworkers (Bogarde) agrees to go into the isolation tank; when he emerges, he is told things about his wife that, if he believes them, will threaten his seemingly happy marriage.
The film holds one's interest; with his science fiction bent, it has the distinctive '60s stamp on it.
Mary Ure plays Bogarde's wife. The acting is good, with the usual fine performance from Bogarde, a man who, once he got away from Rank, was attracted to unusual roles and unusual films. This isn't as wild as it gets for Bogarde. It's not great, but it's not bad either.
