Hollywood treats falling buildings like falling trees [1]. The building basically gets cut off at the base, then stays together as it falls to the side until it hits the ground. I'm no expert, but IRL I think any significant amount of lean would lead to massive structural failure in your average skyscraper. Once the structure starts to fail gravity is going pull the pieces straight down since nothing is pushing them to the side. It's certainly a danger to surrounding buildings (see the WTC) but vastly different from buildings falling over on their sides to crush their neighbors. 1: https://youtu.be/r0tgEYiTNd4 https://youtu.be/r0tgEYiTNd4 (0:35 and 0:45)
