9. “The ones that love us never really leave us.” (Harry Potter and the Prisoner of Azkaban, 2004)

It's one of the most important themes in the books, and in the hands of any less terrific actor than Gary Oldman it could have been forced, stilted, and clunky - but when Gary Oldman as Sirius Black, Harry Potter's godfather, puts his hand on his godson's chest and delivers this line, it's a strike right over home plate.
