What’s the name of the movie if there were two scenes: one – the main character is reading Playboy from the 1950s, and sees girls in there who become old women in his mind. The second is him sitting and watching a girl in a stadium, falling off it and fantasizing about her
I found it myself, it’s “More Ants in the Pants”, or Knallharte Jungs in original.
Glad you found it!
