as >>7739231 its up to you how you structure things, but if your structuring it like a movie beat for beat, Id expect it to be more or less 300 pages for a 90 minute movie, through comparing it to other comics that have been adapted to movies.

Watchmen was 450 pages long, and was turned into a 2 hours and 40 long movie, where as Jojos Phantom blood is 3 hours long in total, and is 950 pages long, so honestly, the content in your pages is probably gonna change that too.

Manga styles tend to have less going on ,and focus on big moments, like a 2 page spread of a cool guy swinging a sword, where as comics might have an entire fight on a 9 panel page

Point is, it could be a good idea to look at storyboards and see how their structered, I'm in the same boat as you, in that I've tried to pace my own comic more like a movie, than as a comic, but in truth, I probably know as much as you. Probably just start drawing, compare your work to others, and learn as you go
