With the immense budget that films and TV shows invest in special effects, it’s hard to imagine a series spending just $64 an episode on special effects. But Blake’s 7 did just that, back in 1978. It was a science fiction show with an unbelievably low budget, but it went on to influence the genre to this day. Elements first introduced in the series can be seen in today’s hit sci-fi shows from Firefly to Star Trek.
