Not quite a genre movie but might be interesting.
Its called Miss Meadows starting Katie Holmes as a very polite very friendly Teacher-who is also a murderous Vigilante.Its a Dark Comedy Thriller that to me at least looks kind of fun-even if it has a look to it.
Katie Holmes is an actress i think a lot of people don't like-but i have always had an affection for. Shes a suprisingly engaging comedy pressence, and while she certainly doesn't look like wonder woman, shes good at using her kind of frail appearence and willowly demeanor. This could be interesting, though i am guessing probabbly not that actiony
its coming to limited theaters November 14th-which i suspect means like video on demands pretty soon after.
