The step sister of one of my high school gfs went to the school at the same time as Rockwell but didn't know he was a professional actor until we all watched "Galaxy Quest" together, at which point she recognized him and said he was the class clown and a really hilarious dude. She was also there with Margaret Cho (maybe the most famous alumnus, along with Aisha Tyler from "Archer") but said Cho never really went to school, preferring to cut class and get ####ed up (which was still pretty common at the school even by the time I got there- our test scores were always through the roof though).
I'll get around to "Shape of Water" eventually but am basically expecting to have the same opinion I always have re: Del Toro- it will look amazing but will alternate between dull and corny.
I'll definitely see the Churchill film but like "Dunkirk" (which I also haven't seen), it sorta seems like an assignment. Will also check out "3 Billboards", "The Florida Project" (anyone see that one?), "I Am Not Your Negro" and maybe "Wonder Wheel", "The Post" and "Killing of a Sacred Deer"
