Other mistake: The bank clerk with the grey hair, offering the cigarette and sitting back is supposed to work in "the late 70's" according to the narration. Surprised to see him again in the audience (front right) of the panel discussion on March 14, 2008, some 30 years later, looking not a year older. (00:01:35 - 01:53:40)
Factual error: In the aerial shot of an overpass in Las Vegas, right after the scene where the cast drives off in taxis, an Avicii billboard is visible in the background. Avicii only grew to fame after the housing market crash. (01:30:00)
Continuity mistake: At the end of Margot Robbie's scene she picks up the champagne flute from her bathtub. The camera angle changes and she is no longer holding it, then picks it up again.
Continuity mistake: When Jared is demonstrating the CDS/CDO using Jenga blocks the pike is standing, then shortly afterwards it's knocked over.
