Maybe Dan Aykroyd wasn't supposed to call anyone. The new "Ghostbusters" reboot has been filming in Boston with a new cast, but now it has been confirmed that one of the OGs is joining the Paul Feig film -- although it sounds like he won't be playing a Ghostbuster. Dan Aykroyd -- who co-wrote the first two movies and played Dr. Raymond Stantz -- was seen filming on set, then confirmed his involvement in a tweet sent July 14. But then he deleted that tweet about two hours later. Oops? Perhaps it was an unauthorized spoiler of a cameo that was meant to be a surprise?

Indie Revolver first shared the news on Dan's cameo, posting this report on Tuesday (WARNING: SPOILERS AHEAD):

Our good friend on the set, "The Twirp" has exclusively revealed to us that Aykroyd is cameoing as a Cabbie in the new film and that he was on set filming his scene last night. The scene featured Kristen Wiig attempting to gain access to Aykroyd's cab in vein. At some point Aykroyd throws out the iconic line, "I ain't afraid of no ghosts!" and drives off with Wiig yelling something along the lines of "That's a double negative! That means you ARE afraid of ghosts!"

The same day, Dan tweeted: "On GB set shooting my scene with funny beautiful Kristen Wiig lady GB'S are adorable, hilarious and badass Exhilarating! #ghostbusters." He deleted that tweet, but his reps confirmed to Entertainment Weekly that he will be in the movie. There has been no further comment from the studio or director Paul Feig.

Dan still has some tweets up about the new "Ghostbusters," but they are from the start of filming on June 19:

"Ghostbusters" is scheduled for release on July 22, 2016. What do you think about Dan Aykroyd joining this movie, but (apparently) not as Ray?
