This year on the Fox TV show, 24 (which I am a big fan of), there are at least three Iranian actors/actresses.
they are:
Necar Zadegan http://www.imdb.com/name/nm2464261/ who plays the role of Dalia Hassan.
Navid Negahban http://www.imdb.com/name/nm1041023/ who plays Jamot and had his first episode tonight.
Nazanin Boniadi http://www.imdb.com/name/nm2258164/bio who had a small role in two episodes.
Good job on being part of this epic TV show which will end next month.
