Didn't realize the movie was two hours long.

Seems weird for a character with gray hair to be referred to as a young man.

The thought of a quiet night being interrupted by a scream and glass shattering seems like something that would keep me awake if it happened.

Also, I'm not sure why one couple is sleeping outside on the fire escape all the time. (Though I suppose the heat could have something to do with it)

Lowering a basket from the third floor seems like an irresponsible way to let your dog do its business.

I should watch more Hitchcock movies - I haven't seen Vertigo.

Now Jefferies has moved from watching his neighbours with his eyes to using binoculars, and even a zoom camera lens.

Jefferies really doesn't know how to get a romantic mood going when one of his questions is "just how would you cut up a human body?"

I don't think I picked up on the heavy implication that Lars Thorwald was having an affair when I first watched the movie.

I like how all of the music seems to be diegetic. (Not sure if that changes by the end or not)

Oh, that poor dog.

Even knowing what's going to happen, the ending (from when Thorwald arrives in his apartment when Lisa's still in it onwards) is really tense.

Especially with the lack of music.

You'd think by the third flashbulb, Thorwald would learn to shut his eyes.

"Creel! Give me your .38!" and another officer just tosses him a gun.

I was concerned it might drag, but the movie went by pretty quickly, especially in the last hour.
