It Chapter 2: 15 Insane Hidden Details You Definitely Missed
1. The Missing Pennywise
In the first movie, right after Henry Bowers and his gang attacks Ben and carve into his belly and the Losers help patch him up, we see a now notorious appearance by Pennywise in the mural on the wall behind them. One minute he's not there and next he's under the wheel arch of the car right behind Ben.
It's a lovely touch, but it's not the last time the mural is important. In the sequel, we see it again, but as a wonderful little touch, the Pennywise that had appeared as part of the painting is now conspicuously missing again.
