One of the holes left unanswered in The Dark Knight Rises comes from the elephant in the room everyone expected and Christopher Nolan refused to touch, "what happened to Joker?" Nolan believed it disrespectful to Heath Ledger's legacy to include any mention of him in the film, so just left it alone. Say he hadn't though, and wanted to add him into the mix...how would he go about that? Sam Saxton has the answer. With some CGI, dark lighting, and a few recorded laughs, Saxton feels this would've been a tasteful and quick way to resolve the issue of the lack of Joker in the escape scene from prison. Would you have liked a Ledger mention in the film?
