Other mistake: During the final shootout in the saloon, young Joey yells, "Shane, look out!" Alan Ladd whirls around and his gun goes off. But the gun isn't pointed anywhere near the bad guy who is standing on the second floor balcony. Shane more than likely shot the furnace that was off to the right. Yet, the bad guy still manages to do a face plant on the barroom floor.
Revealing mistake: Just after orange-yellow letters announce George Steven' production of 'Shane' there's a dissolve to a long shot over the valley floor. Under the last credits a deer is seen in the middleground, farmstead behind and mountains in the distance. Cut to child stalking deer, cocking gun and aiming. Cut to ground level, with deer turning head so antlers frame approaching rider - then a tiny car is seen crossing in the far distance.
