This documentary was shown immediately before a screening of the film in 1998 on Channel 4 in the UK. Although it doesn't spoil the film outright, it does reveal significant parts of the plot. For someone who's never seen the film before, the best advice is to give it a miss. For everyone else, it gives a valuable insight into how TUS was funded, written and produced; from it's incept as an idea discussed between Brian Singer (Director) and Christopher McQuarrie (writer) at the Sundance Film Festival, through it's arduous production process (where it was turned down by more than 130 different production companies), and on to it's eventual success as the best film of the nineties.
