First up was a runaway bus -- something Bullock is very familiar with from her "Speed" days -- that collided with a truck being used for the movie, which saw 15 people suffer minor injuries when a city bus slammed into a production vehicle.
Just days later there was a much more serious incident, with an argument among various men aged 17 to 21 culminating in a fatal stabbing, with an officer on the set actually helping to chase down one of the suspects.
Boston police say one man was killed and two others were injured after a fight ensued just one block from where "The Heat" was filming. One "fictional" officer working on the set actually helped chase down a suspect. All of the victims were between the ages of 17 and 21.
An onlooker described the crazy scene as follows: "The director took the bullhorn and called everyone together. He said three people were stabbed and one of them had died. People were stunned and then the crowd broke up."
Another onlooker reported the following for a story in the Boston Herald: "...a young guy on the ground and people giving him CPR. They were pumping his chest. It looked like he was only about 14 years old. It's so sad, he's just a baby."
Bullock's hasn't been quite as busy as she was in 2009 -- when she managed to win an Academy Award for her role in "The Blind Side" as well as a Razzie for "All About Steve" -- with just "Extremely Loud and Incredibly Close" in 2011 and "Gravity" and "The Heat" currently in post-production.
