When we spoke with Kristen Stewart way back in 2009, she talked about starring in her mother Jules Stewart's directorial debut K-11.  Her description of the role:

"I play a young girl who is not a girl. Her name is Butterfly. She's autistic and that's it. That's Butterfly."

As enticing as that sounds, Stewart's schedule got crazy, so she is no longer Butterfly.  However, E! learned that the Twilight star will appear in the movie, albeit in a very minor capacity---what Jules Stewart calls a "micro-cameo."  You'll hear her voice as the secretary of "a dissipated record producer (Goran Visnjic), who finds himself locked up in L.A. County's notorious K-11 unit, which specializes in special protection for LGBT inmates."  Older brother Cameron Stewart will also appear in a role credited on IMDB as "Sledgehammer."  This movie will be freaky.

Hit the jump for details on Assumed Memories.

Variety reports that Casper Van Dien, Barbie Castro, Armand Assante, Eric Roberts, and William R. Moses have started shooting Concord Films' indie thriller Assumed Memories.  The logline provided is wonderfully abstract:

"Bernard Salzman is directing from his own script, which explores the fatal assumptions that can be made in the absence of proof."

It's even better if you read it like I did, as a math major.

Van Dien is producing alongside Bernard Salzman and Eric Castro.
