In bringing "Macbeth" to the screen, Welles made several changes to Shakespeare's original. He added sequences involving the witches to increase their significance. At the beginning of the film, they create a clay figurine of Macbeth, which is used to symbolize his rise and ruin. It collapses in a heap, seemingly of its own volition, immediately after Macbeth is beheaded. The witches seem to cast a spell on the doll, and anything that happens to it seems to happen also to Macbeth, as in voodoo. The witches also return at the end of the film, viewing the drama from afar and uttering "Peace, the charm's wound up" as the final line; this line is spoken in the first act in the original text, when the witches initially confront Macbeth.
