Forever young Maybe if he hadn't crashed his Porsche 550 Spyder in 1955 after making just three films, we'd think of James Dean the way we do Marlon Brando - aging into puffiness and puffery, with a few dazzling roles lighting up a dimming career. But after that fatal crack-up on a California highway, he'll always be 24. Dean's iconic image was sealed in Nicholas Ray's 1955 melodrama Rebel Without a Cause, in which he played a disaffected teen and launched a lasting vogue for T-shirts, jeans, and mumbled eloquence. The film screens at 7 p.m. at the County Theater, 20 E. State St., Doylestown. Tickets are $10. Call 215-345-6789. The film also screens at the Ambler Theater, 108 E. Butler Ave., Ambler, at 7 p.m. Thursday. Tickets are $10. Call 215-345-7855.
