Bernie Wrightson's Frankenstein (1983)
Bernie Wrightson drew the definitive, visual interpretation of Frankenstein's Monster as a spec project that he sold to Marvel Comics in 1984. He used only Shelley's descriptions and his own research for inspiration and worked on it over a three-year period in between other assignments. Despite its initial (and also it's most recent) publisher, it's not a comic, but an illustrated version of Shelley's novel with introductions by both Wrightson himself and Stephen King.
It was reprinted by Underwood-Miller (a scifi/fantasy small press that dissolved in 1994) as one of their final projects and again as a hardcover by Dark Horse in 2008. It's an essential part of any Frankenstein fan's library.
This British made-for-TV movie is most notable for starring David Warner as the Creature, Carrie Fisher as Elizabeth, and John Geilgud as the old, blind man. It was shot on an extremely low budget, but it does well in spite of that. Warner is a sympathetic Monster who's horrible appearance is explained by his being burned by the electricity that brought him to life. You can watch the entire thing below.
By the way, this was my 3000th post. Yikes.
