Ex-Venkman no longer afraid of no ghosts. By Brandon Wolfe Bill Murray has famously spent the past two decades refusing to suit up for another Ghostbusters , much to the consternation of fans and Dan Aykroyd. But now it seems that Murray’s hesitation to appear in another Ghostbusters film merely hinged on actually having to strap on a proton pack because the actor is now slated to appear in Paul Feig’s currently filming Ghostbusters reboot. Murray was recently spotted heading toward the Boston set of the film to shoot a small part. However, don’t expect to see the actor reprising his iconic role as Dr. Peter Venkman. Birth Movies Death claims that Murray will be portraying a paranormal debunker named Martin Heiss, a role written expressly for the actor. Murray joins fellow former boy-in-grey Aykroyd, who also recently shot a cameo for the film. That just leaves out poor Ernie Hudson, but he has to be used to that by now. The new, female-driven Ghostbusters arrives in theaters
