I already have the shot of him walking away.... From the sandstorm deleted scene footage

I'm only guessing but wouldn't it be better quality if we reshot it? Though to be honest I didn't realise that shot was even available in the deleted scenes so it is probably best to use proper footage wherever possible.

Can anyone suggest a star wars fan-film where Vader chokes a general or admiral of a star destroyer I need this footage...

I don't but I will add it to the list of ideas to film if nobody can think of some footage for you.
