"And the set was made of this stuff. It looked hard but it was soft. It was foam. And my stunt knives were rubber so they didn’t like take out the grip or the camera operator. But we found like…I’d always throw them and Russell Bobbit, the props master, would always go and retrieve them for me for the next take. And he couldn’t find one of the daggers and we were like looking all over the set for this dagger. And I’m like where the hell did it go? And like about half an hour later we’d thought we lost it somewhere in the green screen. And he said, Tom, and he pointed up and this rubber knife was stuck clean into the set, so I knew I was throwing them with some kind of velocity."
