Betelgeuse, Beetlegeuse, Beetlejuice

Rating: 8/10 (13 January 2006)

What's in a name...
Anyone ever notice that the character Betelgeuse has his name spelled "Betelgeuse" (as seen in the movie on his tombstone and the sign pointing to it), but is repeatedly spelled differently throughout this site? Even the official cast overview lists him as "Beetlegeuse" some bastardization of the title "Beetle Juice" and "Betelgeuse." (How is it spelled in the credits?)
I only write this because I'm curious if anyone knows why they would have called the movie "Beetle Juice" rather than "Betelgeuse" other than the obvious marketability of the former?
I'm sure that the original writer had Betelgeuse, the big red star in Orion in mind while writing, but does anyone know more?
