It's amazing what you find out when you watch 44-year old movies, isn't it? For comparison for those of us who feel old.
- King Kong (1933) —> 44 years —> Star Wars (1977) —> 44 years —> Now
Star Wars (it wasn't subtitled "Ep IV: A New Hope" until years later) put Harrison Ford on a star trajectory, but it was the back-to-back releases of
The Empire Strikes Back (1980) and
Raiders of the Lost Ark (1981), that made Harrison Ford a "movie star".
Raiders proved he was "bankable" and could carry a movie in a starring role, without creatures and star fighters. After that he had a solid career of mostly hits.
While Tom Selleck may never had become a major movie star, he did become a TV star and household name with
Magnum P.I. and other series. He had already made the pilot for the series before auditioning for
Raiders, and he had to drop out of the running to play Indy when the series was picked up by CBS.
Whats important for the rest of us to understand is now nearly all content is available at any time. DodgerGirl and others will discover Han Solo and Indiana Jones in the same rabbit hole that may also turn up Buster Keaton or Spongebob or Kazaam. They will discover these things out of order and outside of a historical timeline or context. And all of this is a side-effect of the relatively new (15 years?) concept for streaming and on-demand content. (It's also why we add disclaimers to some oldercontent to give necessary social context).
