According to Joystiq, Betheseda has filed trademarks for the name FallOut for a television series and motion picture. While that doesn’t mean anything is set in stone, it does mean the idea and talks of a future television show or movie is being started.  I haven’t played FallOut 3 yet, but it does like an interesting premise with a style and feel of its own.  If there is a tv series or movie, hopefully along with cool special effects, they include great characters and storylines.
