There's a poetic justice to the fact that allegedly Disney's head is frozen in a suspended state, while his namesake company is essentially focused at this point only on re-animating intellectual property from the 40s, 50s, 60s, and 70s where many of the original talent involved (not to mention the original cultural context) has moved on.

Ah. Let's generously say that did happen and it works out for him at some indeterminate point in the future.

Would you then consider the frozen and completely inactive head disconnected from a living body vital for sustaining the living processes of the head of Walt Disney still living in the present? If this thread is to be completely pedantic, we have to go all the way here.

In the UK a lot of work remains in copyright for the life of the creator (plus 70 years)

If the creator never dies, then the work doesn't go into public domain.

I could see that as a Disney strategy.
