Sandra Bullock is hoping her new movie will encourage Hollywood to make more female led films.

She has teamed up with Melissa McCarthy in The Heat, which is being billed as a female buddy cop movie.

Peter Feig, who also directed Melissa in Bridesmaids, joined Sandra on the red carpet at the movie's London premiere.
