it appears to be mainly US based (for now), but Dr Seuss Enterprises (DSE) is taking a dim view of photographers creating Christmas sessions for children with The Grinch in them. DSE owns the copyright and trademarks to The Grinch name and likeness.

One parent has taken a different tack, by setting up a GoFundMe to raise $15 Million for charity, hoping that this will make DSE let him get away with the shoot. I assume he will go to the media and say how bad DSE are if they don't want him raising money for those in need. Manipulation at its finest.
