For several years, while Sony was developing their Ghostbusters reboot, it was believed that original Ghostbusters star Bill Murray would not appear in the movie. It appears that all has changed, with The Hollywood Reporter confirming that Bill Murray has arrived in Boston to shoot a cameo in the reboot. No details about his appearance were given, and it isn't known if he will portray Peter Venkman or a completely different character.

Last month, we reported that another original Ghostbusters star, Dan Aykroyd, will cameo as a New York City taxi driver, who picks up Kristen Wiig's character, Erin Gilbert. The scene reportedly features Dan Aykroyd saying the classic line "I ain't afraid of no ghost," with Gilbert replying, "That's a double negative! That means you are afraid of ghosts!" Since Dan Aykroyd isn't playing Ray Stantz, it seems unlikely that Bill Murray will portray Peter Venkman.

Rumors suggest that Bill Murray is playing a character named Martin Heiss. The character has been described as 'the villain', and is comparable to William Atherton's Walter Peck from the original movie, a "professional ghost debunker." After he sees some of the videos these new Ghostbusters post online, he becomes determined to prove that they're fake, and "ends up at odds with the team through the whole film." These character details have yet to be confirmed, so stay tuned for more information.

Kristen Wiig will be joined by Melissa McCarthy, Leslie Jones and Kate McKinnon as the new Ghostbusters in this highly-anticipated reboot. The supporting cast includes Chris Hemsworth as their new secretary, Andy Garcia as the Mayor of New York City, along with Michael K. Williams, Matt Walsh, Pat Kiernan and Neil Casey. The reboot is believed to have no connection to the original franchise, which explains why Bill Murray and Dan Aykroyd are playing different characters.

Paul Feig is directing Ghostbusters from a script he co-wrote with Katie Dippold. It isn't known how much shooting is left before the movie reboot heads into post-production, but Sony Pictures has already issued a July 22, 2016 release date. While we wait for more details to emerge, check out these photos of Bill Murray arriving in Boston.
