Happiness Comes In Small Doses, Folks
The following 12 actors are pretty awesome when nibbled as amuse bouche. I'm recognizing the greatness of these actors in ensemble pieces, roles with less screen time, or even just bit parts. That's not to say all of them should never have leading roles. That's not to say that there haven't been better cameo performances. It's just that when shining in brief glimpses, these actors and actresses tend to be at the top of their game.
