._. It's a Tim Burton movie. Beetlejuice (a homophone of the constellation) is a "human exterminator" for the underworld.

Essentially, imagine a chauvinistic guy living in a trailer eating greasy food and watching TV...who has the tongue of a salesman and the power of a high-level poltergeist. Then imagine his plans blowing up in his face.

(A more light-hearted cartoon that removed the chauvinistic part was also released)

You summon or banish him by saying his name 3 times.
