Saw the documentary The Year of the Yao recently at the Toronto film festival. An entertaining look at Yao's rookie season, the film seems more suited to the casual fan, as I didn't see much I didn't already know. And what I didn't know (Yao's relationship with his white American translator, his parents and his girlfriend, say, things which had some emotional impact) wasn't fully developed.
I also wondered why the film is so late in its release given that Yao's rookie season was 2002-2003: it will reportedly be released theatrically in 2005, by which time we will have passed the Year of LeBron James and be in the Year of Somebody Else.
