If the fimmaker are still looking for a distributor, they should stop looking and just fund their own distribution with a Kickstarter, tThe company who make the pen&paper roleplaying game Pathfinder (sucessor to DnD) started a Kickstarter campaign to fund an Online game yesterday and gathered their goal - 50 000$ - in one day. So I think a movie about Larpers starring geek celebrity such as Summer Glau and Peter Dinklage could EASILY get the fund needed for at least a limited release.
