Hundreds took part in an open casting call for "Patriots Day," Mark Wahlberg’s upcoming movie based on the 2013 Boston Marathon bombings.

The casting call began at 10 a.m. Sunday but people started lining up as early as 4 a.m. So many people showed up, police had to eventually shut down Braintree Street.

Wahlberg, a Dorchester native, is both starring in the film and producing it, along with Academy Award winner J.K. Simmons. John Goodman was recently cast as former Boston Police Commissioner Ed Davis. The movie also calls for thousands of extras and many locals showed up to try out. 

"It’s absolutely important because this is where it happened," said James Corbett. "This is where it needs to be."

Among the hopefuls were some police officers and first responders. Angela Peri, owner of Boston Casting Inc., said having actual first responders in the movie will add authenticity.

The movie will begin filming in and around Boston next month. Those picked to be extras will get $100 and a hot lunch for 12 hours of work.
