We see Jared Leto as the Joker decked out in a purple suit with bright green hair driving a neon pink sports car.
At one time it was even rumored that the Joker would cameo in Suicide Squad only in prison, but those rumors seem to be a long way off as, apparently, Joker seems to be more of a rock star.
Check out the images and video below.
Updated: with additional images and video.
Update #2: WB has blocked the video, which shows Joker and Harley Quinn arguing. A man then comes over to see what's going on (I think with a tire iron in hand)with Harley then shooting the man. Joker disarms Harley and then puts the gun to his own head. He puts the gun in his front pants and then smacks Harley and gets into the car.
Update #3: Video is back up.
Update #4: Jared Leto Joker tattoos confirmed.
