The title is deliberately misspelled. This is a big reveal later in the film.

Reposted with a better description.

Some clarification: I mean it's literally a reveal in the film that the title is misspelled. If you just read the title without watching the movie, you would have no idea it's meant to be spelled some other way.

Hint: the reveal that the title is misspelled comes near the end of the movie, close to two and a half hours in.

Okay, final hint since no one's gotten it yet: the film title is someone's name. We find out way later, near the ending, that that's not how their name is spelled.

Not Frances Ha, not Beetlejuice (or Beetlejuice Beetlejuice).
