Visible crew/equipment: In the opening scene you see an old ship in the water, if you look closely you can also see the shadow of the helicopter that is filming the scene.
Continuity mistake: At a meeting to do with the hospital's dealings, one man, Mr Broadbeck, objects to the Elephant Man being a patient in the hospital - in the beginning he is wearing spectacles, but, a few seconds later, the spectacles are gone.
Factual error: In the ambush-on-the-prison scene, one of the Boers is equipped with a Lee-Enfield CLLE Charger-Loading Rifle. Although the Boers used many captured Lee-Enfield and Lee-Metford rifles, the CLLE's weren't even developed until the Boer War had ended.
