Emma Watson was left nursing a foot injury on the set of Sofia Coppola's new movie The Bling Ring after a stiletto-wearing extra stood on her toe.

The Harry Potter star plays one of the so-called 'Bling Ring' thieves, who snatched more than $3 million (£1.9 million) worth of goods from the Hollywood homes of celebrities including Paris Hilton, Lindsay Lohan and Orlando Bloom, and in one scene Watson heads to a nightclub to party.

However, the actress was left covered in blood after a clumsy co-star stood on her foot - but Watson remained a true professional by carrying on with the shoot.

She tells Teen Vogue magazine, "We were doing a scene in a nightclub and this girl accidentally put her stiletto through my toe! And the crazy thing is, I had so much adrenaline going through my system that I just kept dancing until, finally, I looked down at my foot and saw the blood."
