Purely from a business perspective, at $100m, even with Christian Bale, this “promises” to lose a lot of money.
It’s a worthwhile story, but not at that pricetag.
Saw an interview with Christian Bale this morning.... he says that entire proceeds of movie are going to be given to charities. On a quick search, here is one of many articles that says the same thing. http://deadline.com/2017/02/the-promise-elton-john-film-proceeds-nonprofits-aids-foundation-academy-award-party-1201927149/
