(written from a Production point of view)
Opatoshu enjoyed a career that spanned five decades, almost a hundred television guest appearances, and forty-five movie and television roles. His Semitic features and knowledge of the Yiddish language led to frequent roles as Jewish or Arabic characters. Well known roles include Menachem Begin in Raid on Entebbe, and one of the lead characters in a 1980s miniseries about the Roman siege of Masada.
Prior to his Trek appearance, he co-starred with James Doohan in an episode of The Twilight Zone, entitled "Valley of the Shadow". He also starred in a 1981 episode of Buck Rogers in the 25th Century directed by Vincent McEveety in which Barbara Luna, Sid Haig, and Felix Silla also appeared, and in an episode of Ricardo Montalban's Fantasy Island. He also guest starred in an episode of The Time Tunnel, starring James Darren, Whit Bissell and Lee Meriwether. He also had a small role in the Oscar-winning 1958 film, The Brothers Karamazov, which also featured Harry Townes and William Shatner.
