I think you seem to have missed the point that a red-skinned, horned headed devil character has been around long before the Legend movie ever was even thought of. The Christian church would then hold the patent on that....perhaps he should contact the Pope as well? If this is marketed as a "devil" character there is no problem. Styles may be similar in design without infinging on copyrights. You will note that there are already distinct and obvious differences between this character and the Legend one, as noted with the legs and feet / hooved or human. There is no need to clarify and issue which is obviously already clear.
