There are many Hollywood studios currently planning movies based on video games but no TV shows. This is about to change as Bethesda may be pushing to make a Fallout TV series.
Bethesda has filed a trademark on January 8th for “an on-going television program set in a post-nuclear apocalyptic world.” Since Bethesda publishes the Fallout video game series, this suggests they might be planning to make a TV show based on the franchise.
Fallout 3 voice actor Erik Todd Dellum tweeted the other day that something interesting will be coming for fans. Many assumed it would be another game but he may have been referring to the TV series all along.
