Continuity mistake: When Lucius descends the stairs to greet his mother and Commodus, there is a brief close-up sideways which shows, behind them, a banner, and two stones with hieroglyphs. There are in fact several Egyptian obelisks in Rome, that were taken there in antiquity. The only trouble is, it doesn't match with the long shot at all. (Commentary track confirms this was not shot on one existing location - only the four top steps of the stairs were really there). (00:57:31)

Visible crew/equipment: When Commodus enters Rome in triumph, he descends from his chariot to mount the stairs. A group of children with flowers rise. At the extreme right, modern scaffolding is visible for a half a second. (00:57:28)

Revealing mistake: In the shot of the discussion (literally) over the dead body of Marcus Aurelius (horizontal in the foreground), the "corpse" is still breathing. His belly is rising slowly up and down.
