Speaking with People Magazine, Bruce's Wire Room co-star Oliver Trevena had nothing but praise for him.
Admitting that it was always a dream of his to work alongside him, he said: "He's an icon in the action world, in the movie world. So getting to be in a movie with him in a prominent way was, as I say, it's a bucket list checked off."
He maintained what a great guy Bruce is, on and off set, saying: "The guy in general is just a humble, lovely, brilliant man."
