When filming The Empire Strikes Back in Norway, an intense snowstorm hit the hotel the cast and crew were staying in.

Yoda’s species is never named. A mystery, it is.
“I have a bad feeling about this” became a running gag for the franchise and a variation of the line appears in every Star Wars movie.
