Yesterday it was reported that Days of Future Past director Bryan Singer hasn't actually signed onto direct the sequel X-Men: Apocalypse. Well now according to The Daily Superhero he and FOX are currently in negotiations due to his request to receive part of the ticket sales on top of his payment.
This shouldn't come as a surprise since most directors after a certain time with a studio request ticket sales as well. Micheal Bay currently gets 8% of the ticket sales for his work on the Transformers films. Anyway expect them to come sort of agreement soon. He is currently signed onto write and produce Apocalypse at the moment.
