We already get them: Whiplash, Baby Driver, Inception, Arrival, The Martian... Those are just a few of my favourites from the last decade or so but the list goes on!
They all had an established director, producers, and/or actors. It’s a safe risk because studios (from this list fox (rip)) can either bank on the casting list/director history (baby driver, the Martian, arrival) or have it as their one “cinema” film for awards season. Theres a lot missing for 10 years of film that just didn’t take off.
Also Memento was a $9 million dollar movie, even in 2000 that wasn't a lot of money.
What we're missing these days are what myself and my buddy, who's a film buff and writer, are the 10-30 million dollar films. Well written, competent director and director of photography, a reasonable cast of most likely newbies but they can act, and a decent plot/story....Memento, Donnie Darko, The Hurt Locker. Jeez the Hurt Locker was just a 15 million dollar movie, but it's pretty decent (I've watched it five times).
