I'm looking for a 90s (?) horror movie about a woman hired to restore a painting. As she rubs away layers of paint, she reveals a hidden monster that had been painted over.
I seem to remember them movie having a gothic feel / setting. I think she was in a church or castle or something. There may have been a lake nearby.
But really, any movie where a woman rubs away layers of paint and discovers a monster of legend hidden in the artwork is probably right.
