With Beetlejuice 2 already underway, one of the franchise’s original in-universe rules suggests that Beetlejuice 3 will be impossible to pass up. While it took 36 years for Beetlejuice 2 to finally happen after Tim Burton’s 1988 horror-comedy, the sequel actually coming to fruition wasn’t too surprising. Beetlejuice’s original ending left open the possibility of Michael Keaton’s titular ghost returning, with countless opportunities for him to keep wreaking havoc on the living and dead alike. The cult classic has also maintained a strong place in pop culture over the past 36 years, with a new generation being added to the focus of Beetlejuice 2 through Wednesday's Jenna Ortega, whose character provides an enticing future for Burton’s franchise.
