TONIGHT'S MUST-SEE

"The Princess Diaries" (2001), 7 p.m., ABC. When this pleasant little movie soared at the box office, Hollywood tried to copy it. It wanted teen films, girl films and royalty films. None has come close to the $100 million success of "The Princess Diaries." Adapted from a popular book, it had an automatic following. It had two steady pros — Garry Marshall directing and Julie Andrews in the role of the queen mother. It also had a likable young star. Anne Hathaway (who's slated to star in "The Devil Wears Prada" opposite Meryl Streep) plays a San Francisco teen, a good-spirited outsider living with her single mom. Then she learns she's the princess of an obscure kingdom. The story that follows is simple and enjoyable. Marshall does tend to let it drag — a fact that won't be helped by ABC's decision to let this stretch over three hours. Still, it's good enough to fill a Saturday.

OF NOTE

"The Day After Tomorrow" (2004), 5 p.m., HBO, and "Godzilla" (1998), 7 p.m., NBC. Roland Emmerich puts slick, energetic action on the screen. Except for "Independence Day," none of his films have scored big. Now we can choose between two of his films. NBC's has a creature being nasty. HBO's has the weather being nasty.

"Pulp Fiction" (1994), 5 and 8 p.m., Bravo. Here's another chance to see this great and fierce film. Quentin Tarantino started with a clever (and Oscar-winning) script about the exploits of two hit men, a boxer, a mobster's wife and two thieves. John Travolta stars, with a stunning supporting cast that includes Uma Thurman, Ving Rhames, Tim Roth, Harvey Keitel, Amanda Plummer, Bruce Willis and a searing Samuel L. Jackson.

"Big Brother," 7 p.m., CBS. It's the second Saturday for this summer reality series.

"O Brother, Where Art Thou" (2000), 7 p.m., TNT. Joel Coen stylishly directed this Depression-era tale with rich use of old-time folk music. George Clooney and friends escape from prison and go on the lam.

"Saturday Night Live," 10:30 p.m., NBC. This is billed as "the best of Christopher Walken."
