Technical goof!

In 7 SLAVES AGAINST ROME (1964), one of the moments which started the slaves revolt in the story was with the scene in the screenshot above. A slave falls to his death, which upsets everyone and they overturn the oppressive Roman forces. Well, the scene in the top screenshot was originally from PONTIUS PILATE (1962) and re-used for 7 SLAVES. And as you can clearly see the man is shirtless. But for the following scene in 7 SLAVES AGAINST ROME (below), the man is wearing a full tunic. As the man falls you can see he's not wearing many clothes so when you see the following shot with him fully clothed well it stands out for all the wrong reasons. They already had the scene so how could they mess it up?
