“Rarely has a movie this expensive provided so many quotable lines.” So wrote Roger Ebert in his review of Ghostbusters , the 1984 blockbuster that handed our paranormal fears over to some of the sharpest comic minds of the day. Ghostbusters instantly resonated with audiences thanks to eye-popping special effects and crackling wit; to date, it remains the highest-grossing horror comedy of all time. The film spawned an Emmy-nominated Saturday morning cartoon, a tentpole 1989 sequel, a contentious 2016 reboot, legions of merchandise, and one of the most dedicated fan bases in history. Ghostbusters also elevated its players to superstardom, something a few cast members found more daunting than the Stay Puft Marshmallow Man. Now, for the first time, the entire history of the slime-soaked franchise is told in A Convenient Parallel Dimension: How Ghostbusters Slimed Us Forever . The cohesion of talent during the mid-’70s comedy revolution, the seat-of-their-pants creation of the first Ghostbusters , the explosive success that seemed to mandate a franchise, the five year struggle to make Ghostbusters II , the thirty-one-year struggle to make Ghostbusters III —it’s all here, with incredible attention to detail. Thoroughly researched and engaging, A Convenient Parallel Dimension smashes long-held myths and half truths about the dynamics behind this cultural juggernaut and presents the real story, down to the last drop of ectoplasm.
