It looks like he'll be a cab drive that Kristen Wiig's character is trying to get into. He won't let her in and they begin arguing when Aykroyd says "I aint afraid of no ghosts." To which Kristen replies, as he drives off, "That's a double negative! That means you are afraid of ghosts!"
Not sure when his remake is coming out, sometime next year I'm guessing, but they are surely filming it now.
