You're telling me none of these pale skinned mofos got a sunburn?

It's a movie.

They're at a far northerly latitude, where there's less UV and less power in the sunlight.

Yeah and most popular movies these days have guys and gals who wear capes that don't get caught in revolving doors and machinery.

Sunblock applied before going out. I didn't see anyone brush their hair, but I'm sure they did.

They had umbrellas when the film cameras weren't on them.
