This movie is aggressively mediocre. The casting is all wrong. 48-year-old Donald Sutherland neither plays a convincing dolt nor a rakish heartthrob. He has an American accent but is supposed to be British. Ditto Ruth Gordon. What?!?
The movie is a more a mystery “comedy” than a spy movie. It was made in 1983 but released in 1987. That means even people at the time knew it was a misfire. Avoid!
