Isaiah Mustafa (aka the Old Spice guy) continues to make the most of his 15 minutes of fame. Coming off the announcement at Comic-Con that the actor will be guest-starring on Chuck, he has also just joined the Jennifer Aniston film Horrible Bosses. Of the part, Mustafa says, "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!" As long as he works his Old Spice charm, how could she resist?! Are you excited to see Mustafa get larger roles?
