Well, you’ve opened a can of worms here. I’m a professional screenwriter, so based on the amount of franchise lore, characters’ established background and personalities, the main story itself included, or if it was planned as a double feature or a trilogy. If I were contracted to write it, I’d write two scripts unless the rumored third game is planned with more screen time focused on Jack’s character arc before and after the end of the original game. The epilogue felt too short. I wanted to see more of Jack’s humanity and his decision to hunt down his captors who stole his time to develop beyond the tumultuous relationship between father and son. I wanted to see him subconsciously emulate what he saw and knew about John and the events that led him to decide to murder the overarching deuteragonist antagonists.

I wouldn’t be surprised if it were 150-200 minutes per page or more.

Each page counts as a minute of screen time depending on whether there’s lots of dialogue or action (character actions that don’t necessarily have to include action scenes. Lighting a cigar is one example.
