80's-90's movie with a brains-powered spaceship

Question

I watched this movie when I was young on the Sci-Fi network. It might have been made in the early 90's, late 80's. This movie was not an anime or animation, it had real actors. I think it might have been a trilogy.

Its main character was an obese women captured(?) along with a bunch of other people and she was sent to a RM on a metal table that made her thin and beautiful. She also teamed up with a robot head that fell in love with her (and was kinda pervy) and would unlock the doors for her to escape this place she had been captured.

I also remember there was a spaceship that had 12-8 brains that 'talked' and powered the space ship(?). The space ship and brains were important to the movie but I don't know why.

There were also these worm alien monsters that had been released in this futuristic gladiator arena.

Answer 1

This is the German sci-fi TV serial Lexx which ran for five seasons from 1997 to 2002.

During the pilot episode the obese woman, Zev/Xev Bellringer, was a prisoner made thin and conventionally attractive to serve as a sex slave/robot, but the process was interrupted, and she retained her own sense of self. This character was played by at least three actors during the show's tenure: the two during the pilot, and another when the second actor left the show, and the story was written to explain the character's physical transformation. Zev appears above pre-transformation, and below left post-first transformation holding 790. Xev post-second transformation appears below right.

The robot head obsessed with Zev/Xev is 790, and is accurately described in the OP's question.

The spaceship is a living organism and is the titular Lexx (pictured below). Much of the show's situational comedy derives from the experiences of the main characters living inside a living ship (there are some parallels with Farscape's Moya).

The two other main character's were the chauvinistic, ultra-dweeby & pervy captain of the Lexx: Stanley H. Tweedle (below left), and the somewhat undead emo Brunnen-G space-warrior Kai (below right).
