I really like Cary Grant, but this film came off weak. This is probably Cary Grant's worst performance, although it isn't that bad. Overall, the film comes off more like a series of anti-climaxes and half-assed plot devices. I will give the film credit for it's ambition. The film is actually quite fun to watch, but it feels lifeless and weak and it just sort of falls apart before anything really interesting happens. The love story plot on the boat doesn't really make much sense and gives the film a more experimental film than I would like. I guess it comes off as more a series of events that don't really add to too much. I did like the opening scenes involving the phone call that Nancy Carrol gets. I thought her performance was actually better than Cary Grant's as a matter of fact. However, she does some pretty thoughtless and unrealistic stuff that really didn't help the believability factor one bit. Overall, there are some things I like about this film, but there's ore that I don't like and I cannot quite recommend the movie unless you are a die-hard fan of Cary Grant.
