1 THE SUM OF ALL FEARS Phil Alden Robinson / Paramount 1 week / $31.2 million / $31.2 million to date

PLOT Another Jack Ryan thriller from Tom Clancy, this time with Ben Affleck in the lead as a young CIA analyst who must prevent a plot to push the U.S. and Russia into a full-scale nuclear war.

BOTTOM LINE Moderately successful as a thriller, despite a weak performance from Mr. Affleck; made more effective-and chilling-by real-world terrorist threats.

CAUTION Rated PG-13 for violence, disaster images, and brief bad language.

PLOT No. 2 of three prequels to the original Star Wars trilogy, chronicling the maturation of Anakin Skywalker and growing unrest in the Galactic Republic.

BOTTOM LINE Another mostly disappointing entry in this series that manages to find its footing-and awaken the audience-in its final third.

CAUTION Rated PG for sustained sequences of sci-fi action/violence.

PLOT An adaptation of the comic, in which a genetically modified spider bites a young man, giving him superhuman powers; he learns to harness his new gifts and use them to fight evil.

BOTTOM LINE Above-average superhero tale with likeable characters and a worthwhile message about the responsibility to utilize one's gifts for good.

CAUTION Rated PG-13 for stylized violence and action.

PLOT A blaxploitation parody that pits Internet cartoon hero Undercover Brother against a plot by "The Man" to undermine prominent black leaders through a mind-control scheme.

BOTTOM LINE Silly, refreshingly un-PC, sometimes funny comedy that is not unexpectedly loaded with crude humor and sexual innuendo.

CAUTION Rated PG-13 for bad language, sexual humor, drug content, and campy violence.

PLOT A wild horse in the American West is captured by the U.S. Cavalry and, with the help of a friendly Native American boy, must fight to regain his freedom and protect his herd.

BOTTOM LINE Attractively animated but warped view of history that goes out of its way to paint an unflattering picture of the U.S. Army and the westward expansion.

CAUTION Rated G.

Novelist Tom Clancy's character Jack Ryan has been brought to film three times before: once by Alec Baldwin, twice by Harrison Ford. Ben Affleck now embodies Ryan in the new Clancy adaptation, The Sum of All Fears. To accommodate Mr. Affleck's demographic, the character is now a young CIA analyst new to the agency. Despite his inexperience, Ryan is thrust into the center of a plot to pit the United States and Russia against each other in an all-out nuclear war. A neo-Nazi organization led by a sinister Austrian (Alan Bates, doing the best he can with a canned character) attempts to set the ball rolling with an attack on Ravens Stadium in Baltimore during the Super Bowl. This scene has been the focus of media attention. Although some of the debate is overblown (especially since so few critics will acknowledge the negative effect that images on film can have in other circumstances), the attack scene is resonant in a way that would have been impossible pre-9/11. The rest of the film is a mixed bag. The more weight the plot puts on Mr. Affleck, the less convincing he becomes. The fine supporting cast helps to fill the gaps-particularly Morgan Freeman as CIA director and Liev Schreiber as a "real" field agent.
