Bradley Cooper – who is currently filming 'American Hustle in the city – was horrified by the tragedy which unfolded when bombs were set off near the finish line of the Boston marathon just over a week ago and he has since visited some of the injured people in hospital.
Speaking on KIIS FM, he said: "The thing about Boston is there are four Homeland Security hospitals, so the amount of treatment people got instantaneously after the bombs…I think there would have been more casualties had it been in another city. The reaction time was so fast and the ability was so quick, it was just incredible.
"You can really feel the energy of the city rallying around itself. The amount of care is just incredible."
Bradley also revealed if he hadn't been shooting the movie during the marathon he would have attended.
He said:"I would've been right there, we just happened to be in a town about 45 minutes shooting that day [otherwise] I would've been right there."
