As it stands, the Ghostbusters III film will be gracing our screens a cool 30 years since the first one. 30 years is a long time, particularly when you're trying to get the original actors back on board. Dan Aykroyd spoke recently about how they hoped to get Bill Murray back into his ghost-busting boilersuit for the big occasion but it's now being reported that Murray was less than overjoyed with the new script.

Murray allegedly took the script, shredded it, and then returned it to one-time partners Dan Aykroyd and Harold Ramis with the note: 'No one wants to pay money to see fat, old men chasing ghosts!'

Yowza! Sure Ramis has gained a few pounds, but way to go for the jugular Bill! In any case, Bill is also the most successful of the three by far, Dan Aykroyd is now better known for his interest in UFOs and many of the Ramis results on Google refer to his more rotund figure.

But oh no Mr. Murray, you go ahead and shred these poor men's last shot at the good life. I'm sure they weren't that fussed anyway. Just trying to get the old gang back together again for one last hurrah and you had to go and shit all over it didn't you?

Apparently the movie will still go ahead without him anyway.
