- Previous existing IP
- Intention to make multiple films in same story
- Big name talent
- $75-200M production budget
- $30-100M marketing budget
=
4X ROI in box office, nearly every time.
What's NOT required (but helps)
- A great script
- A really great director
- An actor/producer (someone who's very invested into the project)
- Adapting the IP from a book (not previously on screen) OR redoing really bad IP (E.g., Christopher Nolan doing Batman after a few not so great versions)
