I always find it fascinating to hear about roles actors have taken that require three or more hours in the make-up chair, particularly when it looks like they're just wearing costumes (particularly masks). Especially when Mike Myers played The Cat in the Hat or when Jim Carrey played The Grinch. The costumes seemed to cover their whole bodies, Though I feel like it looks like they would have had to put their eyelids underneath the costumed eyelids, which I could see as uncomfortable).
I also feel it's odd when actors who wear fat suits have to spend so much time in make-up before their fully in. Aren't they just getting in oversized costumes?
I know sometimes (like in Back to the Future) prosthetic masks are glued on, so goes it take a long time to glue things on? I was surprised when i got last years Back to the Future: The Ultimate Visual Guide and saw that the main actors spent a few hours getting make-up applied for their 1985 counterpartes. I could see them spending that time for the 2015 counterpartes, but didn't think the 1985 counterpartes looked like it would take that much time. This gets me wondering if they really wear masks, or if maybe they keep putting make-up on faces, maybe freezing them in place until they look right. But would they do this for fat masks (like in The Nutty Professor or Weird Al Yankovic's Fat music video)?
Or maybe I'm underestimating what it's like to get a lot of make-up on and off. After all, I've never worked on any professional movies or TV shows.
