13 - Ed

Played by: Nick Frost

Film(s): Shaun of the Dead (2004)

There's a very real possibility that, had Ed been played by any other actor, he wouldn't be on this list. For Shaun's best friend is, and let's be frank here, an absolute tit, a sponging freeloader who says inappropriate things at the worst possible times, makes hideous life choices, and takes his friends for granted. If he hadn't been played by the innately likeable Nick Frost, there's a chance we'd have been begging for him to be bitten by the end of the first act. As it is, when Ed does go down, there's a note of real tragedy.
