Watch the Ghostbusters record a TV commercial in this new outtakes video

Bill Murray, Dan Aykroyd, Harold Ramis and Annie Potts feature in this behind the scenes video from Ghostbusters.

They are putting together the advert that we see in the final film.

What is interesting are the different company names they use – Ghostblasters – during the various takes. This was because Ghostbusters was owned by Universal and, at the time, Columbia Pictures was still working on getting the rights to the name.
