George got it- it was "HIGH ANXIETY".
It was a comedy that was an homage to Hitchcock, with many references to his films. (I presume I didn't get them all.) The premise is a nod to "Vertigo". One scene took place at an important spot in "Vertigo." We saw a shower scene where someone was attacked in the shower, and the frame-by-frame seems to match "Psycho." An innocent man was framed for a murder (not uncommon for Hitchcock.) The director was in the movie- Mel Brooks played the protagonist (technically not common for Hitchcock, but, whatever.) "The Birds" was nodded to in a whole scene involving pigeons, first congregating in a park on a structure... The name "North By Northwest" was mentioned in the movie. (He could have squeezed a few more names into the dialogue, but he chose not to.)
