28 Days Later - Foreign sure, but indie? With a budget of 8 million and Fox Search Light as a US distributor, maybe. But it picked up steam and played in 1400 theaters and grossed over 45 million domestic. And it's still a Danny Boyle film and he did it for less money on purpose and the DVD is still available on the $10.00 rack right infront of the registers at Target and has sold copies out the ass for the better part of 2 years. It started off that way, but sure didn't end up that way.
Almost Famous - With a 60 million dollar production budget, directed by a big name director, and released in over 2,200 theaters... an indie film? Not even close.
American History X - It played in fewer theaters (500) so maybe, but with a production budget around 20 million dollars and a distribution deal with New Line, it's hard to say that it was really an indie film.
A Bronx Tale - Made for Television but somehow managed to find its way into 1,100 theaters and starred Robert Dinero
Indie films are things that have hardly any studio backing and small budgets. Hardly any of these fit the bill to a tee. So for the sake of argument I'll give you 28 Days later and A Bronx Tale, I'd lean no on American History X. Almost Famous is a definite no.
