It was almost a year ago when last we reported on K-11, the directorial debut of Kristen Stewart's mother, Jules Stewart.  Although Kristen Stewart's potential part was performed instead by Portia Doubleday (Youth in Revolt), Stewart-sibling Cameron does have a role in the picture.  The real standout, however, is the popular Mexican actress Kate del Castillo (Under the Same Moon), who plays a transsexual leader of the titular section of the LA County Jail, an apparently brutal area reserved for homosexuals.  Hit the jump to watch the violent red-band trailer and see the new character poster for K-11 featuring del Castillo.  K-11 will be available on demand and in theaters starting March 15th.

Here's the synopsis for K-11:

Like Alice in a brutally violent Wonderland, music executive Ray Saxx, Jr. is trapped in K-11, a very unique part of the Los Angeles County Prison System. He was out cold when he arrived and he has no idea how he got there -- all he knows is he needs to get the hell out...alive and intact. To do that Ray must navigate through a maze of drug addled-transvestite-criminal politics with obstacles at every turn. Insane cellmates, corrupt officials and his own issues are just a few of what he's dealing with while he pieces together his means of release from this entirely new brand of hell, K-11.
