That little bit of work that I did in the movie, it was in like a bunch of different places: Tokyo, London, somewhere in Morocco, and a little bit in LA. So it was just amazing. You never get to travel like that and be working on an amazing film at the same time. It was a really spectacular experience for sure.”

You can hit me harder, buddy. You can hit me harder than that.’ So the way I had to like get myself [amped up] to really slap him and slapping him.”
