I can think of three main ones...

Dave Nelson from "NewsRadio"

Eric Forman from "That '70s Show"

and

Abed Nadir from "Community" though he hates Episode 1 with a passion.

They are no doubt excited to see the new movie, lol.

Any other characters who are known for loving Star Wars?

The guys from The Big Bang Theory.

Chuck and Morgan from 'Chuck'. I think they both have Star Wars sheets, bedspreads.

Tim - 'Spaced'

Peter Griffin
Seth MacFarlane the creator of Family Guy loves Star Wars

Sheldon cooper the big bang theory

In the final season of "Maude", there's more than one episode where Walter (Bill Macy) and Arthur (Conraid Bain) leave the house to view "Star Wars".
