## Production

During the hiatus after season 3, the writers had a retreat in Lake Tahoe where they planned much of the story arc for the fourth season, mainly mapping out the storylines of the first 10 episodes. In June 2007, the Sci-Fi Channel confirmed the fourth season would be its final season, with an order of 22 episodes, an increase from 13 as originally announced. Production of the final season began in May 2007. A special TV movie, titled Battlestar Galactica: Razor, aired on November 24, 2007. The regular season began airing on April 4, 2008.
Only the first 12 episodes of season four (including Razor, which is technically the first two episodes of the 22 ordered for season 4) were filmed before the 2007–2008 Writers Guild of America strike halted production of all scripted TV shows. After the strike ended, the final 10 episodes began airing on January 16, 2009.
