@hawkeye10,
There is no such thing as a limited release
program. I'm glad you can make things up as you go along.
Each movie production has their own deal with their respective distribution companies.
12 Years a Slave: Fox Searchlight Pictures (2013) (USA) (theatrical)

Silver Linings Playbook: Weinstein Company, The (2012) (USA) (theatrical)

Compare the number of distribution companies each film has worldwide. Your comparison between the two movies and their respective theatrical releases is merely anecdotal at best AKA utterly useless.
Why are you mentioning Thor in the first place? The marketing budget for that movie was $170 million (the rule of thumb being that the marketing budget is about the same amount as the movie production budget).
Hmmm?? David O. Russell? Who's movies are known box office commodities though not blockbusters.
Steve McQueen? He had two other feature films released in the US. Combined US box office total: less then $5 million. Of course he's not going to get any support from the studio system.
