Every dollar of box-office revenue from this Saturday's special movie screening at the Narberth Theatre will benefit the Narberth Community Food Bank, the result of a service project arranged by Narberth's St. Margaret School.

The Mighty Macs, a big-screen depiction of athletic triumph by the Catholic institution Immaculata College (now University) in Chester County, will show on both Narberth screens at 10 a.m. Saturday. Tickets are $5, and each person is asked to bring a can of food to donate, too.

If every ticket sells and every person brings a can, that's at least $2,000 and 400 cans.

"Hopefully we’ll fill the house; that's what we’re expecting," said Anne Becker, St. Margaret's marketing director. "I hope we don't have to turn too many people away."

Based at the United Methodist Church of Narberth, the food bank typically serves 50 people a day in Narberth and Lower Merion, coordinator Gigi Tevlin-Moffat said. 

"This is going to be an over-the-moon kick for us and we are so thankful," Tevlin-Moffat said. "And they came to us! St. Margaret School came up with this on their own. I couldn't ask for better community support."

The event precedes Catholic Schools Week, for which this year's theme is "faith, academics and service." Sony Pictures has given permission for one school per archdiocese to screen the film for charity, and St. Margaret asked first in the Philadelphia area, Becker said. The Mighty Macs opened in U.S. theaters in October.

Among the St. Margaret School community are relatives of film writer and director Tim Chambers and producer Pat Croce. Croce's aunt is the principal, Sister Corinne Ritchie.

St. Margaret is helping raise money for another institution at the same time that many of its fellow archdiocese schools are trying to raise money to survive, such as the efforts by supporters of Archbishop Prendergast and Monsignor Bonner high schools. Those schools are among four dozen recently targeted for closure or consolidation; St. Margaret School was spared.

Doors will open at 9:15 a.m. Saturday.
