Ryan Gosling has a fear of heights, but still did the 150-foot fall at the beginning of the movie.
With 8.5 car rolls, this movie breaks the Guinness World Record of the most car rolls (a fact which Gail actually mentions in the dialogue).
Ryan Gosling had a chance encounter with Steven Spielberg, who told him he loved this movie. Gosling said, "As far as I'm concerned it doesn't matter anymore what happens. Steven Spielberg liked it. That was an all time moment for me. I'm really excited for people to see it. I think it's a really special movie."
"Metalstorm" is a real film from 1983, Metalstorm: The Destruction of Jared-Syn (1983). It even shares the same tagline "It's high noon at the edge of the universe."
