Isaiah Mustafa, the muscle man who's been know to extol the virtues of Old Spice at top volume on TV, has joined Jennifer Aniston and Jason Bateman's new comedy 'Horrible Bosses.'

"It's a smaller role, but who wouldn't want to be in one of these funny, irreverent comedies? The cast is great," Mustafa tells The Hollywood Reporter. "I'm playing a cop because I play these authoritative characters well. I don't know exactly who I'm in the scene with -- maybe Jennifer Aniston!"

'Horrible Bosses' also stars Kevin Spacey, Jamie Foxx and Colin Farrell and is slated to hit theaters next July.
