The Hot Fuzz Blooper Reel
I love movie/TV bloopers. (Previous blooper coverage ahoy!) I also love Hot Fuzz, the Simon Pegg/Nick Frost buddy cop comedy, which manages to maintain its deadpan humor throughout. The joy of the Hot Fuzz blooper reel is seeing how much mirth is simmering just below the surface at all times. Pegg and his fellow cast are one errant smile away from breaking character and collapsing.
This is a thing of beauty. (It's also filled with profanity, FYI.)
