The documentary is called Death in Gaza, and it will be shown a a variety of times on over the next weeks on HBO--here is the HBO decription,   which makes it clear that Martin only saw part of it-

                
DEATH IN GAZA
                
In spring 2003, award-winning filmmaker James Miller and reporter Saira Shah, set out to take a first-hand look at the culture of hate that permeates the Middle East. They captured the lives of three Palestinian children growing up in the bullet-riddled streets of Gaza. Although James and Saira had planned to film the lives of Israeli children as well, in the midst of production, Miller was shot to death by an Israeli tank, falling victim to the very conflict he covered.



Thanks for calling our attention to this, Marty--with luck, I'll be able to catch one of the showings--
