What about a CGI Dr Loomis?
I mean they used that tech for Peter Cushing in Rogue One, wonder if they could make it work for Donald Pleasence in this new one. I'd take just a few min of him in a hospital on his death bed talking to Laurie if they wanted to use the tech sparingly.
I'd just like his character to play some role in this instead of just mentioning he passed away some years ago.
