What a great comedy!
Just finished watching this movie on amazon, and I can't believe I've missed it all these years - what a terrific comedy. I loved the cast, though I think Hawn played it a bit too safe - I don't think she made this the really funny movie it had the potential to be (I can't help wondering if Barbra Streisand, who played 'Doris' in 'The Owl and the Pussycat' would have been better in this role for comedy).
I'm also surprised it got one Oscar nod, and one win - both for Hawn. I thought Bergman and Matthau should've been nominated for their roles. (Matthau had a stellar year in 1969 with 'Hello Dolly' and 'Cactus Flower').
Glad I finally watched this one!
