Part of me is wondering more, if Murdy and his team already have a trilogy planned of sorts.
It could make sense, as the Universal Monsters would not only be extremely easy to use (due to that there isn't anyone to really stop it, outside of if it bombs); but it could be a easy way to reuse assets and props, while giving the service to the iconic group.
Plus, fill in with the motif going on, we have the beast of science against the beast of nature for this round.
