Akira Toriyama left a comment on Dragonball: Evolution before the newest Japanese trailer for the film. ANN translates:
"As the original creator, I had a feeling of “Huh?” upon seeing the screenplay and the character designs, but the director, all the actors, the staff, and the rest are nothing but “ultra” high-caliber people. Maybe the right way for me and all the fans to appreciate it is as a New Dragonball of a different dimension. Perhaps, this might become a great masterpiece of power! Hey, I look forward to it!!"
