1.) Todd Phillips wasn't allowed to reference/use Bruce/The Waynes/Alfred in Joker 2. Dunno if he actually wanted to, but it was a no-go. May account for the tension between him and Gunn?
2.) Tim Hunter from Books of Magic is being used in something (DCU? Zatanna? Constantine 2?), but everything has to be run by someone(s) on the Harry Potter Max series for approval. Odd considering he came first, but obv HP is the brand.
