Bill Murray, Dan Aykroyd Went Joyriding on Police Bikes on Ghostbusters II

“We were shooting the movie about halfway through,” the comedian—who cowrote the movie with costars Rick Moranis, Harold Ramis and director Ivan Reitman—recalled on a June episode of  The Tom Green Farmcast. “Bill Murray and I went up to my house up in Woodrow Wilson Drive above Los Angeles.”
“He said, ‘You have written, and we are in probably, what’s going to be one of the biggest comedies of all time,’” Aykroyd continued. “I said, ‘Well, Bill, we’re only halfway through. How do you know?’”
As for Murray’s response? “‘I know,’” Aykroyd shared. “And he knew. His instincts are amazing.”
