I dont think Trumbull is an ASC, he should be. I spent several years working for the "Commander". I gaffed on a couple of small ride films including Back To The Future - The Ride. the Luxor project (now gone). He used Dave Stewart as hi DP a bunch. Probably one of the Great VFX DP's. Trumbull there's not enough good I could ever say about him.
