Spielberg was a producer on Bumblebee, as was Michael Bay -- the man who resurrected Transformers by directing all five previous movies in the series.

"From a director's perspective he was a dream producer," Knight says of Bay. "We sat down early on and it was great for me, director to director, to pick his brain, to get a sense of his philosophy on the Transformers. He was really respectful and recognized this was someone else's movie, my take on these characters, and the best thing that he could do was to support me and protect me. He let me do my thing, and I'm really appreciative of it."
