I stumbled across a show last night on E! called "Fight for Fame". I can imagine for some actors, seeing it might be intimidating, but to me, it was exhilirating. The show starts with five un-represented actors in L.A. who are vieing for one slot with an Agent. They go through various auditions and exercises and are cut one by one until the winner is left. Each show will have five new faces. The whole process of each episode transpires over the course of one day.
If you have any dreams or delusions of "making it" in Hollywood, I recommend this show.
