UNION CITY – The Park Theater Performing Arts Center has reopened its doors and begun Saturday classes that include ballet, hip hop, Peruvian dance, art, and more. Registration is still open. The Theater, located in the center of the Union City arts district, will expand its seasonal events to add more diverse programs alongside its Passion Play, which has been a tradition for almost 100 years. The theater is also hosting a movie night premiere showing Insidious on Oct. 10 to get into the Halloween spirit, and in December there will be a Christmas show to bring the community together for the holiday season.
