In 2013, Bullock starred alongside Melissa McCarthy in the comedy "The Heat" as an FBI Special Agent who, along with a city detective, must take down a mobster in Boston. It received positive reviews from critics, and took in $230 million at the worldwide box office. Bullock subsequently played an astronaut stranded in space in the sci-fi thriller "Gravity", opposite George Clooney, which premiered at the 70th Venice Film Festival and was released on October 4, 2013, to coincide with the beginning of World Space Week. "Gravity" received universal critical acclaim and a standing ovation in Venice. The film was called "the most realistic and beautifully choreographed film ever set in space" and certain critics considered Bullock's performance to be the best of her career. "Gravity" grossed $716 million worldwide to become Bullock's second-most successful film. For her role as Dr. Ryan Stone, Bullock was nominated for the Academy Award, Golden Globe Award, BAFTA Award, Screen Actors Guild Award, and Critics' Choice Movie Award for Best Actress. On her performance, "Variety" wrote: Bullock inhabits the role with grave dignity and hints at Stone's past scars with sensitivity and tact, and she holds the screen effortlessly once Gravity becomes a veritable one-woman show... the actress remains fully present emotionally, projecting a very appealing combo of vulnerability, intelligence and determination that not only wins us over immediately, but sustains attention all the way through the cathartic closing reels.
