Joker origin movie?! Wait, it gets worse!

I don't really remember fans saying that, but BvS was definitely nothing more than a giant ad for Justice League. They even created the individual logos for each hero in the film. The DCEU is kinda a mess right now. They may have had one success with Wonder Woman but even if Justice League makes money, it'll probably still get panned because it still looks messy and doesn't know what kind of film it wants to be. Now there's a possibility of a stand alone Joker film and not recasting Jared Leto. That kinda already proves Warner Bros doesn't particularly have confidence in their own cinematic universe right now. I don't doubt Scorsese as a film maker, but we've already had a grounded and gritty Joker before, just watch The Dark Knight. What can you do different from Ledger's Joker?
