Capitalizing on the Star Wars phenomenon, ABC debuted its own gee-whiz space opera Battlestar Galactica in 1978. A battle more fierce than humans vs. Cylons began when 20th Century Fox sued BSG’s studio Universal for allegedly ripping off more than Luke Skywalker's haircut. The lawsuit was dropped. The Clone Wars cheekily paid tribute with several droids aping the Cylon catchphrase: ''By your command.'' The circle is now complete.
