Not only is trying to compare every Star Wars actor's success to Harrison Ford's sorta unfair in terms of Star Wars, but in terms of acting in general. Dude was pretty much the single biggest movie star in Hollywood - TWICE.
None of them continued to get leading roles in a Hollywood tentpole pictures.
Two of them
did, and those two didn't seem to be exclusively pursuing that as their primary career path anyway.
Boyega and Ridley are likely going to get to do whatever the fuck they want for awhile, like McGregor did. He didn't "fail" at scoring whatever picture he wanted (and doing well in those pictures) he basically took the financial security as an opportunity to actually pursue all the shit he
wanted to do. So did Fisher, really.
I'm not sure if I would qualify Wing Commander games and voice acting gigs as a great recovery
I said "pretty nicely," though, not "great," so like...
Basically, your whole point is pretty silly. Like there's only one possible career path out of Star Wars and if you don't track with it, you somehow fucked it up. Especially when the career path you're using as a measuring stick is a career path 99.95% of actors, PERIOD, have never even closely approximated.
