Been fascinated by Christian Marclay since he was cutting up vinyl LPs with dental tools and gluing the pieces together to make new records. Tape on records, things glued on. Saw him in 1988 at the Performing Garage, as a turntablist. Saw his "Festival" exhibition at the Whitney 2 yrs ago. Excited to see The Clock when it returns to NYC. Happy that he's getting recognition for his great art mind.
He spent the time compiling all of the footage and editing it together, so yes he did "make" the film. Your sarcastic use of quotes are unnecessary.
