I had the bald cap on, and it was between two soundstages that were just gray boxes of 200-foot walls and sand. It became like a microwave. There were people passing out from heat stroke. And that was just my first week.”

The 32-year-old went on to say, "It really bonds the entire crew. There's something so humbling about being in such an uncomfortable environment."
