In 1981, Ivan Reitman’s ‘Ghostsmashers’ had nearly been completed when John Belushi unfortunately died and production was halted for a few months. When shooting resumed, Eddie Murphy, John Candy and Paul Reubens were unable to reprise their roles due to other contractual obligations (because of Beverly Hills Cop, Splash and Pee-Wee’s Big adventure respectively). Their roles were recast and the movie was finished as ‘#Ghostbusters’. Promotional materials have now surfaced from the vaults of Columbia Pictures.
