Where can I find the sisters grimm movie trailer?

There isn't one, since they haven't started filming yet. I don't think they've even got a cast yet, to be honest. A warning: There are a few videos on YouTube that have to do with the Sisters Grimm. One of them looks very real, but it's just a book report. A lot of people don't realize that, so if you hear people complaining that Sabrina and Puck are too old or something, don't worry: it's not true.
