Beritasatu.com has been reporting on this since at least March, and has a very tiny photo of the two in costume (both dressed as pocongs) Depe also took tot he streets dressed as Catwoman on a motorcycle with a fake Mr. Bean pocong being dragged behind her. Yes, this actually happened somewhere.
UPDATE: This turns out might not be Rowan Atkinson after all! Twitch user soimah has linked to posts on this Indonesian forum showing a picture of a guy dressed up as Mr. Bean that is decidedly NOT Rowan Atkinson. The posts on the forum have a weak argument back and forth as to if it is a hoax, though the general consensus seems to think it is. This means that KK Dheeraj managed to get actual hoax press articles published over months to build up interest in this film. It’s also bad for me, because I now have to apologize. I’m sorry I got anyone’s hopes up that this was real. Maybe there is a miracle and it is, but it’s probably not. It will still be crazy insane, though!
