Alan Rickman In Harry Potter Deathly Hallows Part 1 (2010)
Alan Rickman (as Professor Snape), who was on screen for just 1 minute, 15 seconds in the first Deathly Hallows film, had a total screen time of only 43 minutes in all eight Harry Potter movies.
That whole scene with the girl in #29 made me wince. It was hard to watch, but then so was the whole movie.
This.
