Scenes from Tim Burton's Sweeney Todd have been cut because they aren't "family friendly" enough, reports Cinematical. But just how gruesome is it? Well, the film crew, who have probably seen it all, apparently had to take frequent breaks to keep their nausea at bay. Could an uncut/unrated version of the film be far behind? --Kim
