Like I said someone who was invovled with this ("Roy" Robert C. Ritchie) said this was done on the cheap. However lacking incredibility the re-enacment was the information given was very good. Kudos to Roy, Christine. Gail , Dave and all the others!
And also to my friends Jerry, Louie, Micheal, Dwayne, Frankie and the late Jon Rose for having survived what had to be a miserable filiming experience. Remember they were being paid to do a job and had little or no input on how that job was to be done. :)
As too using the same people in scenes over and over again it isn't only cheap documentaires that this has been done. I saw my friend Mario atttacking himself in the last battle scene in "Master & Commander ..."
