Ford-at times--seemed rather petty. In May of 1983, NBC ran a week-long series of cast interviews leading up to the release of Return of the Jedi, and although Ford said he was grateful to Lucas, he also said (to paraphrase) that he would not be sad not to see the Han costume again. Although Ford starred in Blade Runner while in the SW films, he always came off like one of those actors with a less than pleasant opinion of science fiction, almost as if he wrote it off as some kiddie crap. Perhaps it was the kind of films the SW trilogy were (in his view), or whatever, but he's always had this bitter opinion of the films. That, and he was also a bit self-centered (shocker) in that he's always said the SW films were "Luke's story." Yes, that was true, but that did not wipe away the importance of other characters, or the actors behind them, which his statement would imply.
Either way, if Ford had an issue with sci-fi, I just ignore it, as film history has witnessed many actors--some considered among the greatest (IOW...not Ford) star in sci-fi with no complaints. I think of Charlton Heston, a true legend (waaayyy obove and beyond Ford as an actor) who saw the potential in Planet of the Apes, and pursued other sci-fi films after that film (before someone says he did not want to star in Beneath the Planet of the Apes, that was due to his view that sequels were usually inferior, and that there was no story left to tell after the events of the original). This can be chalked up to a "to each his own" view of actor behavior / desire, however, if Ford never thought SW was worthy as a concept, or of his time, again, I look to other actors who took on roles in sci-fi, and were not complaining about it.
