BBM was released like an art-house movie in the US -- it showed in three major cities at first, and then a handful of other major cities, and then expanded to smaller cities and to some small towns. I saw it about three weeks after it opened, but I had to drive for eight hours round-trip to see it. (Crossed state lines, saw a pair of shooting stars just before desert sunrise... it was quite an experience.) It played in my small town for two months, so when it finally opened here, there wasn't a problem seeing it. But this town was an exception -- I think it may have been one of a handful of towns used to test-market BBM in more rural communities. In some other towns, there were actually articles in local newspapers after the Golden Globes, explaining that the local theaters weren't boycotting BBM, and they would show it as soon as Focus made enough prints available. (But BBM didn't do nearly as well in those expansions, which were the ones right after Oscar nominations came out.) It did show in multiplexes where those were the only theaters around, but it didn't generally show in towns with fewer than five theater screens. If it had won Best Picture at the Oscars, maybe it would have shown in some towns with limited numbers of screens -- some of those towns still get movies really late in the release. But, well, that didn't happen.
The DVD was sold in Wal-Mart, which is the major discount chain store in small towns in America, so it's available to people in small towns even if it didn't show on a big screen. (And the Dave Cullen message board did a big donation campaign to libraries. The Wyoming libraries seemed really happy to get it, and it's now available in libraries in Riverton and near where Ennis and Jack grew up. Some libraries refused copies, a few because they disapproved of the movie, but most for reasons related to their circulation policies (no feature films, for instance).)
