Re: Spring. Flowers return to bloom. College students revisit rowdy vacation spots. And after the January lull, Hollywood releases its first batch of ”quality” movies — notably some hot potatoes whose openings were reconsidered after the Sept. 11 attacks. Expect the likes of Mel, Angelina, Eddie, Denzel, and Julia to reaffirm their star status. Then there’s a new cast of characters, including The Rock and Britney Spears, all reimagining themselves on screen. Even fictional folk are getting into the act, with Blade, Jason, Peter Pan, and E.T. primed for — what else?
