"But I Don't Wanna Get Married" is a surprisingly frank movie about sex. While it doesn't SAY a lot of things, it's very clear that despite being a widower, Walter has some amazing sex!
When the film begins, you learn that Walter (Hershell Bernardi) is a widower and father of two boys. Despite being, at best, an ordinary looking guy, he finds that an amazing number of gorgeous women find him attractive...and he isn't exactly looking for a replacement wife despite proddings from some do-gooders. Eventually he relents and begins dating. The woman his sister-in-law picked out is just god- awful (Nanette Fabray) but soon Walter finds his very sexy secretary coming on to him, his neighbor (Shirley Jones), his youngest son's teacher (Tina Louise) and even a 'professional girl' (oddly played by Joyce Van Patten). And, by the end of the film, he's found a delightful woman more his speed (June Lockhart).
Despite it being very hard to imagine Bernardi being a chick magnet, this is a decent and entertaining film. But I was surprised with his relationship with Van Patten's character. She was clearly a prostitute and it was clear he had sex with her twice! This must have really shocked folks back in 1970 and I am a bit surprised that they got away with this one. Overall, certainly far from a must-see but worth seeing if you are curious.
