Why wasn't Mark Hamill able to piggyback off the original Star Wars films and launch himself as a movie star like Harrison Ford did?

Was anyone around for when Star Wars came out? I'd imagine Hamill being front and center for the biggest film in history must have been offered a shit ton of movie scrips, right? I recall reading he had a severe accident that he had to get surgery on, but did that really damage his shot at being a leading man? Why was the Star Wars trilogy the only films he was the star of back in the late 70s/early 80s? via /r/StarWars https://ift.tt/3tYKyGH
