Yes, Dan Aykroyd will be in the new ‘Ghostbusters’

With filming on the new all-female “Ghostbusters” reboot well underway in Boston, it’s going to be hard to keep any cameo appearances a secret. Especially when that cameo is by one of the original Ghostbusters — and co-writer of the first two films — and when he confirms his participation via Twitter. But then, that’s modern Hollywood for you. “On GB set shooting my scene with funny, [beautiful] Kristen Wiig,” Dan Aykroyd posted to Twitter, though he soon deleted it. “Lady GBs are adorable, hilarious and badass. Exhilarating!”

And if that’s not good enough for you, film blog Indie Revolver actually has the details of his cameo, thanks to an on-set source with very good hearing. There should probably be some kind of spoiler warning here, but: The scene involves Wiig trying to hail a cab driven by Aykroyd, who gets to shout the iconic line, “I ain’t afraid of no ghosts” before he drives off, leaving Wiig to respond, “That’s a double negative! That means you are afraid of ghosts!”

Sounds delightful.
