It’s not news, George Lucas is on record saying he was influenced by Lensmen.
It’s remarkable how forgotten Doc Smith is now, given that he was such a big deal in the 60s.
I've been hoping that Hollywood would discover the series ever since I first read it, back in the '70s. The Anime is nothing like it.
Smith's Lensmen has the same issue that H. Rider Haggard's Allan Quatermain has* -- they would be mistaken as imitations of their descendants (Indiana Jones for Quatermain, every OP space-cop since for Lensmen). Yes, I'm sure if a movie/series came out, it would rapidly spread around the discussion that actually (or ackchyually) lensmen came first. The problem is, generally speaking, no one cares. You don't get special credit** for having the idea first because there's no one handing out credit, it's just what people like or get into.
*in things other than stuff like League of Extraordinary Gentlemen, where being last-century-famous is part of the premise.
**ask Hydrox cookies. Er, well you can't because they're inanimate objects, but you get the idea.
Personally, I would love a Lensman series, new Flash Gordon and Buck Rogers movies, and maybe even an adaptation of
King Solomon's Mines that met with modern sensibilities (honestly, this is the one you might have to set in space for it to work...). However, I have no idea how to make them viable, given that people have been seeing their stories for years, just with different heroes on the box covers, etc.
Little bit of both. While not as bad as some of his cohort, Smith's handling of women was--not ideal. And I'm not sure we ever saw a non-white person among his human characters (though maybe he just didn't describe them in enough physical detail for it to show).
(And as others have mentioned, you at least need to handle the whole Arisian thing very--carefully).
Sure. Its the question of what you decide to keep and get rid of that's the question. Do you toss the whole Red Lensman thing out completely, or have her distinct for some other reason? There's other elements that raise those sorts of questions, too.
I think, like 90+% of US IP before a certain time, Lensmen never included a non-white character when it wasn't specifically relevant to the plot, and wildly overused women as helpless characters or femme fatales. However, I don't recall any of that being vital to the premise or important storylines. It would be easy to do a Lensmen series without these problems.
