Wonder Girlfriend (1993)

comic book illustrator Simon Loui loses job and girlfriend is pissed off about him. So he gets drunk and wishes upon a star ... just as a spaceship is flying overhead, and an alien buzzes out and follows him home. Using his comic drawings on the walls as a guide, the alien assumes human form (to become Jacqueline Law) and calls herself Mah-Hey. Girlfriend gets understandably upset and walks out. Artist and Mah-Hey get jobs in a new firm, where she gives him support and help to succeed where he failed before. In between, Mah-Hey drinks water by the large bucketload, occasionally helps artist win fights, and looks into his dreams while he sleeps.

Unfortunately the movie Wonder Girlfriend is not yet available on HBO Max.
