>Sundance

For 10 days every January, total strangers will turn to the person next to them on a bus in Park City, Utah, and ask, "What have you seen that's good?" They're seeking help–anyone's help–in narrowing down some 100 movies unspooling at the Sundance Film Festival. This year, films worth catching included:

•Green Dragon, an eloquent drama about Vietnamese refugees at a U.S. resettlement camp.

•Memento, an intricately structured thriller that tells its murder story backwards.

•The Business of Strangers, in which two women (Stockard Channing and Julia Stiles) on a business trip play nasty mind games.

•Enigma, a sleek WWII thriller about British code-crackers (Dougray Scott and Kate Winslet).

•The Caveman's Valentine, for Samuel L. Jackson's bravura turn as a crazy homeless man.

•Haiku Tunnel, a wily-comedy about a hapless office temp.
