"Il tigre" ("The Tiger and the Pussycat") is an Italian film starring Vittorio Gassman as well as Ann-Margret and Eleanor Parker. It starts of VERY badly, with some god-awful music that is very offputting. My suggestion is that you mute your TV during this intro!
Francesco (Gassman) is a successful man with a lovely wife (Parker). However, after his son tries to kill himself over a woman, Francesco sees the same young woman and goes gaga. Soon he's having an affair and throwing his life away for this woman. But the woman (Ann-Margret) isn't THAT serious about him and he begins to smother her with demands). As for the wife, she knows what is happening but hopes by ignoring it that he'll get the other woman out of his system and return to her. Instead, Francesco pretty much throws everything away, including his job, for the other woman.
The film is a comedy...even though my summary sure doesn't sound like it. I think the humor is supposed to be in watching Francesco make a fool of himself. For me, it was occasionally funny but overall I was a bit bored by it after a while. Not a terrible film but a slightly below average one.
