The entire 1960s Batman television series will be available on Blu-ray. All 120 episodes have been fully remastered in HD for this limited edition set that comes with 3 hours of bonus footage, an Adam West scrapbook, trading cards, and more. 120 episodes is a lot for a show that only ran 3 seasons. It takes the average show about 5 seasons to get to around 100 episodes. The high count is due to the fact that the network split the original hour-long episodes into two half-hour parts that would run in the same week. It seems like an evil plot thought up by the Joker, but it was really just a way of creating cliffhangers that would increase ratings.
