Which actor provided the English voice of Altaïr in the first Assassin's Creed?

Philip Shahbaz provided the English voice of Altaïr in the first Assassin's Creed.

Shahbaz voiced Altaïr Ibn-La'Ahad, the game's historical protagonist and a Syrian member of the Assassin Brotherhood. Altaïr's story takes place during the Third Crusade, and the character's missions form the historical-memory sequence experienced through Desmond Miles and the Animus.

Altaïr's English performance is sometimes confused with other prominent Assassin's Creed voice actors. Roger Craig Smith voices Ezio Auditore in the English versions of the Ezio games, while Nolan North voices Desmond Miles. Michael Fassbender starred in the 2016 Assassin's Creed film, but he did not voice Altaïr in the 2007 game.

The first game was developed by Ubisoft Montreal and released in 2007. In later appearances, Altaïr's voice performances and actors can differ by production, language, and medium, so the question specifically concerns the original game's English voice cast.
