I am new to this post and have an interest background with early Canadian film history (I am a film technician at the Library-Archives of Canada).
I am also doing research into the Canadian Army Film Unit and am in the process of building a portion of my website devoted to the men and women who made up these units; http://www.canadianfilm.com/cafu/canadian_army_film_unit.htm
There is an interview with James O'Regan and links to the DVD 'Shooters'.
In the near future I will also be selling t-shirts of the Canadian Army Newsreel and if anyone is interested please let me know and I will make sure they are provided a link to the store when they are ready for sale. I am hoping to offer them with a custom bookmark, and military dog-tag.
Although my research at the moment is spotty on the CAFU I highly recommend O'Regan's DVD.
Looking forward to sharing more information on the film unit in the coming months.
