availability

i'm currently doing a project on film adaptation. one of the projects i chose was giant. i plan to talk about the cultural impact of giant - one great example of course is come back to the five and dime jimmy dean, jimmy dean.

i was suprised to not find this on vhs or dvd on ebay. the only time i heard of it being played was once on tv and at the afi silver theatre.

does anyone know where i can find a copy of this film?
