IT (Stephen King's) - Softbox Lighting in Glasses
There are many shots in this film, dozens, where we can see the rectangular reflections of the softbox lighting in the eye glasses of the kids and adults.
It's not unusual to see lights reflected in film, but usually some effort is made to make the reflection appear to be from a plausible source. But in this film, it's always the rectangle shape and no effort is made to vary it or attribute it to a plausible source.
There is one exterior/outside shot where we can see a reflector board in "fatty's" glasses, and also the grip's thumb holding the board in position.
Lots of instances. Too many to list.
