Sandra Bullock was on location in Cambridge, MA, yesterday while filming The Heat. She chatted with a production assistant while leaving her trailer to film some scenes. The movie is a buddy cop flick in which Sandra stars opposite the Emmy-nominated Melissa McCarthy. Bridesmaids director Paul Feig is also involved with the film, which will be Sandra's first comedic turn since 2009. She took a break to focus on more dramatic roles, including her part as an engineer in Gravity. George Clooney portrays a veteran astronaut in the sci-fi thriller, which is scheduled for release in 2013.
