Will Summer Glau help or hurt The Knights of Badassdom?

Actress Summer Glau has been cast in The Knights of Badassdom, an upcoming movie from director Joe Lynch (Wrong Turn 2: Dead End). Glau is the first female actor to join the odd-sounding horror comedy, which follows a group of LARPers (live-action role players) who somehow manage to mix it up with what are described as "heavy metal demons," according to Bleeding Cool. The cast already includes Peter Dinklage, Danny Pudi, Steve Zahn and True Blood's Ryan Kwanten.

We love the Texas-born Glau, who's well known to audiences for her role as River Tam in both the Firefly TV series and its follow-up movie, Serenity, as well as for playing a deadly female Terminator in Terminator: The Sarah Connor Chronicles. She's also had recurring roles in Dollhouse and The 4400 and has been cast in NBC's upcoming midseason superhero drama The Cape.

But though the exotic-looking, somewhat mysterious Glau is quite popular with fans (which could be good for The Knights of Badassdom), none of her series (with the exception of The 4400, in which she was not a main character) have lasted more than one or two seasons (which is not so good).

There's no word yet on when The Knights of Badassdom will begin production or hit the screen, but it's also confirmed that effects shop Spectral Motion, which made monsters and mutants come to life on pictures like Hellboy and X-Men: The Last Stand, will create those "heavy metal demons." And Ms. Glau will be there to kick their heavy metal butts.

So considering Summer Glau's track record with doomed sci-fi TV shows, is this a casting coup—or a casting curse?
