Almost Famous (2000)

Continuity mistake: Toward the end, Russell goes to talk to William at his house. He turns the chair around to sit on it backwards, and throws the shirt down onto the ground. When he sits down the shirt is back on the chair.

Elaine Miller: Keep the small bills on the outside and call me if anyone gets drunk.
William Miller: I will call you if anyone anywhere gets drunk.

Trivia: Penny Lane picks up William to go see Stillwater at the Riot Club in L.A. In the very beginning of the scene in her car, a reflection passes up the windshield over William's face as they are driving. The Reflection is the prism and spectrum from Pink Floyd's "Dark Side of the Moon" album. There are no other reflections in this scene.

Question: In the Sabbath backstage scene when Stillwater is leaving, is that the band manager played by Jimmy Fallon following the band out, before he was introduced as their manager in the timeline?
