Alexander Siddig played Dr. Julian Bashir, a graduate of Starfleet Medical and a brilliant specialist in multi-species medicine. He graduated second in his class and could have gone anywhere, but due to his naivete and his zealous expectations of adventure, he chose the remote space station Deep Space Nine. "Julian is a humanist, and a bit of a philosopher," according to Siddig. "He's confident and incredibly enthusiastic about medicine. Although, along with that level of confidence, there is a certain youthful arrogance as well."

Born in Sudan and raised in England, Siddig was a student of the London Academy of Music and Dramatic Arts (LAMDA), and appeared as the lead in such productions as "Hamlet" and "Arthur." Upon completion of the three year program at LAMDA, he joined the Manchester Library Theater in London, where he appeared in productions of "Brother Eichemann" and "Sinbad the Sailor."

Still in London, Siddig then went on to try his hand at directing, and made his directorial debut at the Arts Threshold Theater with productions of "Lotus and the Rats" and "Julius Caesar." During this period he was called back to acting, only this time on television. In 1991, Siddig made his TV debut in the independent British television production of "The Big Battalions," a three-part drama. He also appeared in "A Dangerous Man: Lawrence After Arabia" which aired on PBS.

In 2000, Siddig appeared in the action-adventure feature film "Vertical Limit."
