The actor also spoke about using therapy to relax after a long day on set.
He said: “I’m amping myself up all day long, and then my nervous system doesn’t know that I’m not lopping people’s heads off. For me to relax and sit still is next to impossible.”
Jason can next be seen in the rebooted sci-fi epic Dune and confessed to being stunned after seeing the first trailer.
“It was, ‘Josh Brolin, Jason Momoa, Javier Bardem,’ and I’m just like, ‘Oh my god. I can’t believe my name was with those names’. I feel like I’m still a kid, freaking out.”
