While most businesses are closed for Christmas Day and part or all of Christmas Eve, some retailers will leave the lights on to offer meals, movies and more. Christmas is a big day for entertainment, which means local video rental stories and movie theaters will be open for business.“It’s one of the busiest times of year,” said Kim Haynes, manager at Movies 400 in Cumming. “It’s a good way to spend time with your family.“Not everybody celebrates Christmas either and there’s no place to go ... it’s usually busier than a normal Saturday.”Big Christmas releases include “Gulliver’s Travels,” “Little Fockers” and “True Grit.”
