In case you haven't heard, Rob McElhenney (Mac), Glenn Howerton (Dennis R. Reynolds), and Charlie Day (Charlie Kelly), the boys of It's Always Sunny in Philadelphia, are currently working on a new show called Boldly Going Nowhere which will air on FOX. However, they won't be starring in the comedy since they'll be serving as executive producers instead.
Boldly Going Nowhere will reportedly be a mix of comedy and sci-fi and will revolve around the day-to-day life of the captain of an intergalactic spaceship. Adam Stein, a writer's assistant on It's Always Sunny in Philadelphia, came up with the original idea and will share a created-by credit, though McElhenney, Howerton, and Day will do much of the writing. The pilot was shot in October and, so far, FOX has ordered five additional episodes.
