Continuity mistake: In the scene where Stallone gets hit by the UFC fighter, he doesn't see the hit coming because he gets hit from his right side. Later on, when driving his girlfriend home from the restaurant, he is still blind in his right eye and doesn't see the car coming from the right. However, during the Grudge Match, he is suddenly blind in his left eye.
Factual error: The bikes used in film are Enfield Classics, which were introduced in 2010 and not available in 1960 or 1947. The engines are visible in 2 scenes (when young Milka meets his sister for first time in Delhi and when Milka rides to see his old home when in Pakistan) and are AVL engines, not the cast iron engines in 1950s bikes.
