Revealing mistake: Mueller hops off his horse and tells Tintin (as Amed) to hold the horse and tells him he will be back in a moment. Throughout the entirety of this shot, the colour of the blanket on Mueller's horse constantly flickers between several frames. As Mueller gets off the horse, the blanket is dark teal, then Mueller hands the rein to his horse to Tintin and the blanket suddenly flickers to dark orange and also dark teal near the bottom. Tintin jumps off the horse and the blanket suddenly flickers back to dark teal again. (00:13:25)
