Continuity mistake: Right before the chariot race, Sheik Ilderim is on Judah's left side, pointing out the spikes on Messala's wheels. There's a shot of the wheels and then back to Judah, where the Sheik is now on Judah's right side. Judah holds the Sheik's forearm as the fanfare starts. Then a long shot, showing the Sheik, now on Judah's left side again, and Judah removing his hand from the Sheik's forearm.
Suggested correction: The sheik actually moves around the chariot to the right side. No continuity error.
You can't assume that the sheik moves. It's not shown and the shots are so quick in succession the sheik didn't have time to move.
