Well i have seen this one when i saw FOTR for the forth time
"When the troll stabs Frodo in Balin's tomb, the spear pierces him on his left side, but when Aragorn pulls him up, the tear on his shirt is on the right side."
and this one from TTT " After the attack by the wargs and Aragorn has fallen off the cliff, we see him floating in the river. When he reaches the bank, we see his wound is on the left arm. When he arrives at Helm's Deep and talks to Gimli whilst on his horse, his wound is on his right arm. It changes between shots from the river scene to the scene at Helm's Deep. "
