Director John Depew said he was filming a scene at a North Andover convenience store last weekend when police officers suddenly stormed in to apprehend their suspects, Boston's WCVB-TV reported Sunday.

"They came in and they said, 'Drop the gun' and I couldn't see the officer because he was behind (me)," Depew said. "I said, 'It's a movie, it's a movie -- we're filming a movie!'"

Depew said two actors playing robbers for the last Sunday's scene were placed in handcuffs by the officers, but were released after the situation was explained.

WCVB-TV said the confusion was brought about by a mistaken 911 call from an unidentified individual who said an actual robbery was taking place at the store.
