BEST BETS FOR SUNDAY, AUG. 22, 2010

	DATELINE NBC NBC, 7 p.m ET This week is loaded with special programs devoted to the fifth anniversary of the landfall of Hurricane Katrina, and here’s one of the first. Brian Williams, whose reporting at the time was both memorable and passionate, hosts this one-hour retrospective, which is personal as well as historical.
	SWISS FAMILY ROBINSON TCM, 8 p.m. ET I saw this movie in theaters when it came out during Christmas week in 1960. I was seven years old, and thought the treehouse in this Disney adventure movie was one of the coolest things ever, and I wanted to move there. Fifty years later, I still do. I wonder if it has wireless?
	RUBICON AMC, 9 p.m. ET Who is Donald Bloom? I have no idea – but according to the promos, someone is looking for him in tonight’s episode five. Maybe he’s related to Leopold Bloom, the hero of James Joyce’s Ulysses. On this show, I wouldn’t rule anything out, even if it’s unlikely and obscure. ESPECIALLY if it’s unlikely and obscure.
	TRUE BLOOD HBO, 9 p.m. ET Eric has to defend his women, and himself, in tonight’s episode, which has many powerful vampires descending to wreak vengeance upon those who did harm to the Magistrate.
	LEVERAGE TNT, 9 p.m. ET Tonight’s episode is called “The Rashomon Job,” an overt and fond salute to Akira Kurosawa’s 1950 drama, which told the same story from various conflicting perspectives. So does this show, as the team members provide very different takes on an old scam.
	MAD MEN AMC, 10 p.m. ET Series creator Matthew Weiner is fiercely protective about the contents of each week’s show, but the promos have leaked one important revelation: Somewhere in here, making her first appearance in weeks, is Don’s ex-wife, Betty Draper.
