The-Dark-Knight
Super Freak
Yeah, I think publicity shots were bronze belts but those used in the actual film are clearly yellow, we even get a close up shot of it.
Usually the pre production shots are taken before the film starts filming, so I imagine these shots are those that were used for action figure lines like kenners dark knight collection. That said toy biz's line of figures had the yellow belt.
After all that though, again its clearly yellow on screen.
