That's correct about the Vader... VERY full size! Big guy. Have to say the vac formed mask was beautiful in person. Clever way to cut down weight and looked amazing in person.
I realize you were just picking other nits to have a go at the Vader folks and I don't want to go nit-for-tat (ha!)... but...
The Tonnika sisters' costumes are actually blue and green in the film (just that most stills we've seen were black and white or improperly colorized) and the band head (which is a prequels-used mask supplied by Lucasfilm) was wearing a beige scarf that just LOOKED like the bib untucked
Just having fun here though. I agree totally that the folks on set and in production did some great work and I know the costumer tried her best to get the closest she could that time (and budget) allowed. The set was just INCREDIBLE considering how quickly it all came together.
best,
Tom
