Source Code movie trailer released

Check out the official trailer for the movie Source Code.  Keep reading for the story line and details.  The movie looks pretty good.  I am just trying to wrap my head around the name “Source Code”.  Since I am into geeky computer tech stuff including coding and web development, I am hoping by watching the movie it will make sense and that they are just not arbitrarily giving the name Source Code because a “computer program” is running this identity crossover program….

Story from the Source Code Official Website:

WHEN DECORATED SOLDIER CAPTAIN COLTER STEVENS (JAKE GYLLENHAAL) WAKES UP IN THE BODY OF AN UNKNOWN MAN, HE DISCOVERS HE’S PART OF A MISSION TO FIND THE BOMBER OF A CHICAGO COMMUTER TRAIN. IN AN ASSIGNMENT UNLIKE ANY HE’S EVER KNOWN, HE LEARNS HE’S PART OF A GOVERNMENT EXPERIMENT CALLED THE “SOURCE CODE,” A PROGRAM THAT ENABLES HIM TO CROSS OVER INTO ANOTHER MAN’S IDENTITY IN THE LAST 8 MINUTES OF HIS LIFE. WITH A SECOND MUCH LARGER TARGET THREATENING TO KILL MILLIONS IN DOWNTOWN CHICAGO, COLTER RE-LIVES THE INCIDENT OVER AND OVER AGAIN, GATHERING CLUES EACH TIME, UNTIL HE CAN SOLVE THE MYSTERY OF WHO IS BEHIND THE BOMBS AND PREVENT THE NEXT ATTACK.
