Does anyone have any favourite ways that a character is introduced into a film? Three that come to mind for me are
Harry Lime's entrance in The Third Man - when he steps pot of the dark doorway.
Jack Sparrow's entrance in POTC; Legend of the Black Pearl - in the crows nest of his sinking boat, and as he arrives at the pier the crows nest is level with the deck and he just steps off. Brilliant.
Lisa Fremont's entrance in Rear Window:
And Godzilla's entrance in the 1998 Godzilla.
Edit.
Sorry, that's four.
