Super Giant was played in all nine films by respected film/TV actor Ken Utsui. However, Utsui hated playing Super Giant and, right up to his death, always played down the role. This was partially on account of the somewhat embarrassing costume, especially the overstuffed crotch area (he said the producers thought that female viewers were attracted to well-endowed men, so they stuffed the crotch area of Utsui's costume with cotton). Whatever Utsui's feelings about the role, his earnest and heroic interpretation of the character made lasting impact on a generation's children all over the world.
