Jason Altman is one of the executive producers on Mythic Quest: Raven's Banquet. He represents the interests of the main production company, Ubisoft Motion Pictures. As such, he was involved in luring Rob McElhenney into the initial partnership behind the show. He is also the chief liaison between Ubisoft's movie and games division, and the effective executive producer for the in-narrative gaming elements seen within the show.
Much of Altman's experience is with the main games division of Ubisoft, but during the production of Mythic Quest: Raven's Banquet, he was also producing projects based on Just Dance and Skull & Bones for Ubisoft Motion Pictures.
He should not be confused with several other people named "Jason Altman" in the entertainment industry, such as a fairly prolific character actor who looks somewhat like him.
