Trivia: In order to show that Eddie has severe hang-ups about his relationship with his mother, both his mother (in flashbacks) and his wife (briefly seen in the opening) are played by the same actress, Molly Atkinson, albeit in significantly different makeup and wardrobe to make it subtler.
Trivia: Bill Skarsgård has a lazy eye that he was able to train himself to focus in the same direction as his other eye. Thus, when Pennywise's eyes look in different directions, it's not an effect... Skarsgård is just letting his lazy eye naturally drift. His co-star Billy Hader didn't realise this and asked Skarsgård how the effect of his eyes focusing in different directions was achieved, assuming it was CGI. Skarsgård replied, "Oh, you mean this?" and let his drift sideways, horrifying Hader.
Suggested correction: Subtract 27 from 2019 and you get 1992. They were 12-13 in 92 so it is plausible that those games could have been in the arcade while they were still kids.
It's set in 1989, not 1992.
The "present day" scenes in this film actually take place in 2016, 27 years after the first film is set which would be 1989. The mistake is valid.

Some of the flashbacks seem to be set after the first movie.
That flashback definitely was not supposed to be after the first movie, it featured Henry Bowers.

And Pennywise would have been asleep in 1992~1993 so that whole scene after the arcade makes no sense.
