As stated in the title, a woman drops down to her knees then quickly stands up again then drops to her knees again then back up, and repeats this over and over again. I believe this was in the trailer for the film. From what I think I can remember, the scene was very darkly lit and there was some scary music or sounds playing. That’s all I can remember, besides it being a horror/exorcism film. Thanks!
The Exorcism Of Emily Rose (2005). You can see the “knee drops” at 1:55 in the trailer below.

Just remembered I hadn’t commented on this one, it WAS The Exorcism Of Emily Rose. Sorry about that. You can close this topic if you need to.
Great, thanks, Solved!
