"Buddy Buddy", the final film of the genius that was Billy Wilder, is a decent comedy but not a worthy ending to his career. It's a remake of the French film "L'Emmerdeur", but I haven't seen it and am therefore incapable of comparison.
Someone pointed out that the movie looks a lot older than it is. I very much agree.
It is sad to see geniuses like Wilder and Diamond putting something as awkward as genital jokes into their script. Surprisingly, there is one clumsy slapstick moment. There are genuinely funny scenes and lines, too ("Father, you said the F word"), but they are a minority. Some attempts at creating humour fail terribly, as if made by amateurs (Lemmon chair-bound); most merely produce nods of acceptance.
Matthau is good and Lemmon is amusing as expected. However, Paula Prentiss's performance is really disturbing, intentionally or not, and Kinski's character is just annoying - and I mean written that way.
Overall the film, entitled here "Varsinaiset kumppanukset" ("Some Buddies"), isn't nearly as embarrassing as I'd expected; a mere shadow, nevertheless, it is of its director's previous masterpieces - if even that. But be not fooled: Wilder can't go bad (granted, I still have a lot to see). A few, pardon my French, comedy nuggets make this decent as an entertainment, and its two stars are okay. "Buddy Buddy", then, as a title... Meh.
