Definately from kottke.org:
A list of film’s most impressive and famous long takes, including those from Boogie Nights, Touch of Evil, Children of Men, and The Player. Featuring the now-standard YouTube clips of each long take.
There’s alot of clips to view there. A great compilation. I love long takes in movies, especially when it’s more than just a technical exercise. Read up on the section about Goodfellas for example. I miss being a film major in college.
