With Rescue Me's fifth season finally (kinda, sorta) getting closer, we're getting more and more news about what's in store for Tommy and the gang. In addition to the minisodes, we've also got some exciting potential casting news: Michael J. Fox may be joining Rescue Me for a multi-episode arc. Fox is set to play a love interest for Tommy's (Dennis Leary) on-again/off-again ex, Janet (Andrea Roth).

Rescue Me may seem like an odd show for the former Spin City and Family Ties star to pop up on, but Fox and Leary are longtime friends. This friendship means that even though the deal isn't completely finalized, there's very good chance that Fox will be seen on the FX drama next summer.

As AOL Television continues their look at the 50 Best TV Comedies -- Ever with their Top 10, we here at TV Squad are also looking at television comedy, but with a slightly skewed difference. Last week, we took a look at the Saturday Night Live cast members from 1996 to 2006 that made it to the big time. This week, we get a bit more serious.

There are those in the industry who say that it is easier to go from acting in a drama to acting in a comedy than it is the other way around. Yet, as you will see from the list we've compiled after the jump, there are plenty of comedic actors who have jumped from the world of comedy films, stand-up comedy, and television sitcoms into the more serious world of drama. In many cases they have had even greater success than they did on the other side of the tracks. There have even been instances where they stayed in the drama genre and never went back to being funny.
