The cast of "West Side Story" (in theaters Dec. 10) were feeling "oh so pretty" Monday night at the New York premiere of Steven Spielberg's new film adaptation of the beloved Broadway musical. The new take on the classic love story features Elgort and Zegler as Tony and Maria, two young lovers caught in the middle of tensions between two rival street gangs, the white Jets and Puerto Rican Sharks.
