They worship him because he was Luke Skywalker in the original Star Wars trilogy, and those movies are major cultural touchstones in the US. Oddly, he hasn't really been in many onscreen roles since -- his real skill is as a voice actor, and he's had the good sense to lean into that -- but in many people's minds that just identifies him more with the character he played back in the 70s and 80s. It's a very weird phenomenon.
