I am making a haunted house/ghost movie some of the scenes involve objects flying across the room, and door closing by them selves. How exactly can I do this with out have to use expensive special effects software? I think I may have a way to one of the scenes, in the scenes a couple of the characters are playing a board game and then suddenly the board is thrown at a wall. I was thinking that I could make a small hole in the board and insert the fishing line into the hole tie it then pull the line when it is time for the board to be thrown. Would this be a good way to do this scene or is there a better and simpler way to do this?
