The front hull yes, the front turret with HVAP, of which by that time they should have had at least a couple. Some people also say that the Tiger would have hit the front tank first. I'm not sure about that. If the ambushed vehicles were on a road with little space to maneuver out of it the SOP was to hit the first and then the last one to trap the vehicles in between. But in the movie the road was surrounded by open terrain. Maybe hitting the last tank from a concealed position would confuse the ambushed, so it may not be unrealistic. I think the mistake in the movie is that the Tiger would have targeted Fury first because it was armed with the 76 mm and was the most dangerous opponent. Instead the Germans keep targeting the other Shermans. Another mistake is the Tiger firing on the move. The Shermans had a gyrostabilizer, it was not very good but maybe in such a situation it may be possible that they had tried to fire while moving.
