I don't think that mean that Summer Glau will be there at the DIFF but just that the PR agency has understood that Summer is the most buzzworthy actor of LOGH.

Previous articles were on local (texan) medias like Examiner.com or frontburner.com; obviously, ‘Good morning Texas’ is a local network.
What i want to say is that there won't be any national theatrical release for this low-budget film "The Legend of Hell’s Gate" and i highly doubt there will be a DVD-release. LOGH is small fish and Summer Glau has a small role on it.
The complete tweet says there are talks with video production company, which mean nothing.

As a Summer Glau fansite, it's our duty to give news and/or pictures about Summer's work and news, so do we. But there is little to expect from LOGH concerning Summer's carrer. Wining FHM’s 100 Sexiest Women in the World 2011 contest (i hope) will do better regarding make her noticed from producers.

here is the interview

@ 2:11 :
Journalist : "...coming projects for you?"
Summer : "This one and a few others that i'm working on that i can't talk about yet."

I really hope Summer has great projects on the way and that this is not what actors say when it's slow. That and the news of the talent agent switch could lead the way to a great year for Summer Glau.

will it not get a dvd release?, I want to see it.
