When I first saw the previews for this summer's big action/sci-fi movie, The Island, I thought that it looked like a retread of of the 1970's sci-fi classic, Logan's Run. But, apparently it is closer in many respects to the almost forgotten 1979 movie, The Clonus Horror. So close actually, that the producers of Clonus are suing the makers of The Island for copyright infringement.
I haven't seen either of the two movies in question (although the Mystery Science Theater 3000 version of Clonus sounds pretty familiar) but the producers of Clonus claim at 90 instances where the films are identical.
This should make for an interesting copyright infringement case if it ever makes its way to a courtroom.
