Hollywood actress Sandra Bullock is determined to fulfil a lifelong dream by taking a theatre role in London's West End.

The Speed star admits she is desperate to test her acting skills on stage and she would happily move to London to tread the boards in the city's famed theatre district.

Speaking to reporters at the premiere of her new film The Heat in the British capital, she says, "I'm slightly obsessed with London. I've always had an affinity with this place that borders on stalking. I absolutely love it here. One day, I'm going, 'I'm doing theatre and coming to the West End'."

However, Bullock admits her dream will have to wait until her young son Louis is a bit older, adding, "When my son hates me and doesn't want me around (that's when I'll move to London)."
