Bill Murray and Dan Aykroyd are coming back in a third installment of Ghostbusters. At least that's what People is reporting, quoting Variety. Let's hope it's more successful than Aykroyd's attempt to re-energise the Blues Brothers franchise (without John Belushi, on account of his being dead). And, if it's true, let's wait for all those stories to emerge from the set about how "difficult" Murray is.
