On 5 February 2009, Bethesda Softworks LLC applied for the Fallout trademark for “Entertainment services in the nature of an on-going television program” (s/n 77663853) and for “motion picture films about a post-nuclear apocalyptic world” (s/n 77663852). Obviously they already own all the other US trademarks to do with this game property at present.
Fallout, the film. Or the TV series. Hmm. Interesting notion.
