Even though he’s acted in many different shows, I only knew him from Sleeper Cell, a fantastic TV show where he played a definitely not nice guy, and definitely not from the actor's home country of Israel.

I’ve been watching Covert Affairs on Amazon (free with ads), and he is absolutely hilarious, playing a Mossad agent in Season 1, Episode 4. I didn’t know he could do comedy.

I loved Sleeper Cell. I'll have to check out Covert Affairs.
