Arguably, a indie short that probably never was screened theatrically isn’t going to get the same level of scrutiny as a feature film made by 20th Century Fox. I hadn’t heard that ROTN couldn’t use a Vader mask. I guess Lucasfilm objected?
How Fox got away with this, I have no idea.

I thought it was sleazy of them to use Star Wars this way.
