This story is corroborated by one of the film's actors (who requested anonymity) and by Sestero in The Disaster Artist. Sestero describes Schklair taking charge of numerous sequences in which Wiseau found himself unable to remember lines or adequately interact with the rest of the cast, but jokes that claiming directorial credit was like "claiming to have been the Hindenburgs principal aeronautics engineer", and also notes that Schklair left the production before the end of principal photography in favor of the short film Jumbo Girl due to that project being shot by Janusz Kamiński.
