Bethesda Softworks recently applied for additional Fallout trademarks to do with "an ongoing television programme" and "motion picture films about a post-nuclear apocalyptic world".
We've contacted Bethesda for comment, but don't expect much. Our guess is the company is safeguarding the brand, rather than actively making a TV show or film. (Update: Bethesda subsequently told Eurogamer it couldn't comment.)
On the plus side, this is a good excuse to point out that Matthew Perry is biased towards Fallout, having told USA Today about his gaming tip for High School Musical actor Zac Efron:
"The biggest advice I had for him was to start playing Fallout 3 instead of Call of Duty 4. It has more of a story."
Apparently Efron "could not figure it out". Re-roll, idiot.
