OZ vs AOD (and other 'recycled ' plots)
There's an article over at cracked.com discussing the link between OZ/Army of Darkness as well as other directors who did something similar.
They didn't mention :
Michael Mann's Heat (recycles his LA takedown TV movie)
Cronenberg's Existenz (recycles Videodrome?)
John Carpenter's Vampire$ (ending rips off Assualt on Precinct 13 then he went and did AOP13 in space with Ghosts of Mars)
agree/disagree?
Other examples?
