Dan Aykroyd today tweeted that he was filming a scene for the movie that will make Ghostsbusters II the second best Ghostbusters movie.
Dr Ray Stantz himself tweeted the below message (which he has since deleted), but EW later confirmed with his representatives his involvement:
Reports indicate Aykroyd will appear as a Taxi driver who interacts with Kristen Wiig as she attempts to hail his taxi. Aykroyd allegedly throws out the iconic line, “I ain’t afraid of no ghosts” before driving away with Wiig yelling something along the lines of “That’s a double negative! That means you are afraid of ghosts!”
