A new film trilogy is soon to be completed as is in development. This comes after 2024 saw the successful release of the long-delayed sequel Beetlejuice Beetlejuice. This movie followed up the events of the 1988 original film decades later, returning Lydia Deetz (Winona Ryder) to the screen while introducing her daughter, Astrid (Jenna Ortega), and other new characters. The sequel was originally slated after the release of the first Tim Burton movie, but a series of creative changes and delays left it held up for many decades.

When Beetlejuice Beetlejuice did finally come out, . While this nearly ensured the creation of a sequel, Beetlejuice 3 was officially confirmed this year. The threequel could return to the titular ghost and other main characters, and it has the opportunity to delve deeper into the lore established in the first two movies.

There are already some clear rules established in the Beetlejuice universe that create the movie’s idiosyncratically spooky environment, but some of these elements go unexplained. One such bylaw is that This rule is confirmed in the 1988 original film, where Betelgeuse plays charades to try to get Lydia to say his name, but does not provide his name out loud. This element of his character is clearly established, but the reasoning is never explained.

There have been several theories as to why Betelguese cannot say his name. One is that he is not actually a ghost, but a demon. In conventional mythology, Those who know a demon's name give it power over them, which would align with how the Beetlejuice character operates. Making the main character a demon would change the lore, as he self-describes himself as a ghost, but the third movie could take time to explain this or any other justification they may come up with.

Even though he cannot say his own name, other people calling the main character's name is a critical plot detail. As per Burton mythology, This is still true when Astrid is coming of age years later, and accidentally brings the ghost back in Beetlejuice Beetlejuice. There has been some evidence of a previous explanation for why this rule exists, but the movies have not fully fleshed it out.

The Beetlejuice script morphed over time, making some tweaks to make the cult classic comedy what it is now. In the original rendition, a receptionist reads Adam and Barbara the rules. " and it is revealed that the receptionist only has three fingers on each hand, visually demonstrating this clause. This scene may have helped justify why Betelguese's name must be said three times to summon him. The second movie did not return to this scene nor provide more context on the rule, giving Beetlejuice 3 opportunities.

While the third movie does not have a title yet, it seems like the best option would be Beetlejuice Beetlejuice Beetlejuice. After all, this would follow the naming convention of the first two movies and reference a key element of the movies. If it takes on this title, The film would draw more attention to this element, thus allowing Beetlejuice 3 to expand and further explain the trilogy's lore.
