Photos of Bill arriving in Boston, and heading to the set, have also been published online.
Blog Birth.Movies.Death claim to have details of Bill’s role - spoiler warning! - and report that he will play a new character, Martin Heis, adding that it’s “a really tiny role”.
The news will come as a surprise to fans, as Bill previously stated that he had no desire to appear in any new ‘Ghostbusters’ reboots.
However, when Paul Feig revealed plans for an all-female line-up, Bill heaped praise on the director, calling the concept a “swell” idea.
In July, the first snaps of the new team - which consists of Melissa, Kristen, Kate McKinnon, and Leslie Jones - was revealed, and it’s also been confirmed that Chris Hemsworth has also landed a role.
Naturally, some fans weren’t too chuffed when Paul unveiled his ladies-only team of ghostbusters. Thankfully, they’ve got almost 11 months to get over it, which we’re sure is plenty of time.
