What we're watching: NASCAR is the obvious choice tonight, with the Sony HD 500 from Fontana, California taking the primetime slot on NBC. HDNet Movies has an all-Eastwood slate of films scheduled for tonight including A Fistful of Dollars, The Good, the Bad and the Ugly, and Pale Rider. College football kickoff weekend continues on ESPN with Kentucky and Louisville squaring off, while those of us without HD DVD players can check out National Lampoon's Animal House on Cinemax.
