Joseph‘s co-star Jeremy Luke recently chatted about working with him on the film.

“The thing with Joe is, he’s really great because he understands actors. He speaks the same language. We rehearsed for this film, which was cool because a lot of times you get on set and the rehearsal is actual camera rehearsal. With Joe, we had time to rehearse. And the thing with him, I really trusted him,” Jeremy shared.
