Fringe's Lance Reddick made a guest appearance on the FX TV show "It's Always Sunny In Philadelphia" as jazz club owner Reggie.
Reddick is himself a jazz musician when he's not playing an FBI agent on TV.
Also, Zap2it recently got a chance to speak with legendary comedic actor Danny DeVito about "It's Always Sunny in Philadelphia." He made a really interesting comparison for "Sunny" vs. "Taxi," the show he was famous for in the late 1970s/early 1980s.
"It's like... have you ever watched 'Fringe?' says DeVito. "It's like another universe. It's like the same thing, in a way, because ['Sunny' has] really good writing and we had great writing on 'Taxi.' We had a great cast on 'Taxi' and we have a great cast on Sunny. And we have people who really care about each other, but it's just an alternate universe. It's like a kind of a different milieu. A different whole zeitgeist, what goes on there."
