But, as is the case with any sea change, the pendulum might have swung a bit too far in the opposite direction. Instead of opening the field for actors of any race to compete for any role in a color-blind manner, there has been a significant number of parts designated as ethnic this year, making them off-limits for Caucasian actors, some agents signal. Many pilot characters this year were listed as open to all ethnicities, but when reps would call to inquire about an actor submission, they frequently have been told that only non-Caucasian actors would be considered. “Basically 50% of the roles in a pilot have to be ethnic, and the mandate goes all the way down to guest parts,” one talent representative said.
