In Theaters: Journey To 'The Core,' Political Uproar And Mystery In The Corps

'The Core,' 'Head of State,' 'Basic' and 'Spirited Away' open on Friday.

The duo who struck cinematic gold in "Pulp Fiction" reunite this weekend in theaters, where they face competition from an Oscar-winning cartoon, some cartoonish sci-fi action and a cartoonish presidential candidate.

John Travolta and Samuel L. Jackson are back together in "Basic," with Travolta as a special agent sent to investigate the disappearance of several military cadets who left on a training mission under Jackson.

A different sort of mission is at the heart of "The Core," an apocalyptic action thriller along the lines of "Armageddon" that sees Oscar winner Hilary Swank ("Boys Don't Cry") as part of a rag-tag team who must journey to the center of the Earth to stop a government weapon gone wrong that could destroy the planet.

Meanwhile, the Academy Award-winning animated feature "Spirited Away" (see " 'Chicago' Dances Away With Six Oscars; Eminem's Will Be Mailed To Him") goes into wide release, while Chris Rock and Bernie Mac run for president and vice president, respectively, in the comedy "Head of State."

All four movies will go up against the box-office might of Queen Latifah and Steve Martin's "Bringing Down the House," which has been the #1 movie in America since its release three weeks ago.
