Last night, I saw a film called Replicant, which stars Jean Claude Van Damme as a serial killer in which a clone is made from him so that the clone could be used to predict the killer's next moves (he plays both the killer and the clone. Er, obviously).
I watched it in my Film Symposium class because the movie's scriptwriter was there for a Q&A session. The movie never made it to the theaters (if you saw the ending, you'd know why). It's too bad, cause Van Damme actually acted well in that one. And the clone hooks up with a fine hooker later in the film too.
