Iron Forged in Fire: Part One - S1-E1
Continuity mistake: On his first flight with the Iron Man armor, Tony loses control trying to avoid a building and falls towards the road. As he is regaining his flight, the car he is heading right at is a gray vehicle. It then cuts to a close up from the reverse angle as Tony avoids the car and it suddenly becomes a yellow taxi as it swerves and stops in the road at an angle. Then the shot changes again as Tony is flying away and now the taxi has turned into a purple car. (00:16:40)
