As it happens, back in my teens in the early '80s, I independently created my own character named Bill Rice -- the captain of the first FTL ship in my SF universe as it existed at the time. When I discovered that Roddenberry had created a character by that name, I was kind of freaked.
In the 1980s I created a story concept for a dreadnought-style starship that was frozen in time for centuries, and finally emerged to be the light of freedom to an oppressed galaxy.
In 2000 I turned on my TV and did a major double-take.
I had never gotten around to writing the story, though.
