There is plenty of home video footage which probably made it tempting to do a documentary. I am not interested in ballet but to rate it as a documentary I didn't find it too enthralling.
It includes perfectly good archival film so why bother with the dramatisation scenes and therefore water down the films credibility as to the portrayal of the truth?
William Talman is perfectly cast as the threat. No expense is spared on the desert locations or car – but a saving is made on the barking dog which is heard but not seen as it is shot off screen. The simple screenplay has a commendable no frills ending.
