It's apparent that the British love their sex comedies. The U.K. was a veritable hot-bed for the genre. The Confessions series, much like the Adventures Of series, was an R-Rated version of the Carry On movies. Same dated humor but with younger casts, nudity, and the swinging 70's as their setting. I've seen about 15-20 of these films and they all are the same middling British comedies that Canadians and Americans won't get.
This one stars Robin Askwith as Tim Lea, a clumsy young man who gets in cahoots with his brother-in-law over managing an unproven rock band called Kipper. Askwith's job is to get venues and record deals for them and all he does is get into a lot of crazy situations and into the bedroom of some fine women (for the 1970's).
Typically, the acting is filled with double entendres and British humor. Nothing awful but nothing spectacular, either. Interestingly, in this film, Askwith looks like a young Mick Jagger and two scenes in the film extenuate this. In one scene, Timothy needed to replace the drummer for their first gig and he does a pretty good job; enough that he is being chased by groupies. He goes into hiding but one of them finds him and seduces him because she thinks he's Jagger. In another scene, he is in the office of some woman. She asks for a light. Somehow later, the garbage can is on fire and he tries to fan the flames with ridiculous results. He finds an extinguisher and starts spraying this foamy white liquid all over the place and destroys the office. It reminded me of The Rolling Stones' video for "It's Only Rock 'N Roll" where tons of soap bubbles appear on the set. Funny.
It's an O.K. timewaster. I haven't seen the others but I'm guessing like the Carry On series, the Adventures Of series, or the Beach Party with Frankie and Annette if you've seen one, you've seen them all.
