A teaser in December would be six months out though. Bumblebee did relatively well for a winter movie and it’s teaser was 6 months out. Even then, the time between a trailer and release is redundant now with all the film delays because of Covid. Granted, Batman is a larger and more popular property, but we got that teaser a year and a half before it’s scheduled release, and the film was and has been one of the most anticipated films in recent memory. A teaser is December wouldn’t hurt ROTB I think.
