Liked it mainly for Bronson.
I just watched St. Ives for the first time the other day. I'm a Bronson fan but for whatever reason never saw this one. The story at times gets confusing but I really liked how Bronson played the St. Ives character. There's some good dark humor in this movie. I do think Bronson was a bit of an underrated actor and while most are still watchable it's unfortunate he ended his career by making mostly B level action flicks. In the 70s Bronson still made some interesting films that weren't all shoot em ups.
Also Jacqueline Bisset was very stunning.
