Tom Hardy has injured his ankle while filming 'Legend'.

The 36-year-old actor - who portrays notorious gangsters Ronnie and Reggie Kray in the crime thriller was rushed to hospital for X-rays after hurting himself while shooting a fight scene last week.

A source told The Sun newspaper: ''Tom went over on it pretty hard. He's a tough guy but you could tell he was in pain. They didn't take any chances and carted him off to hospital for an X-ray.''

Despite his injury ''giving him grief'', Tom has returned to work on the set in South London.

When his role in the film was announced, the 'Tinker Tailor Soldier Spy' actor admitted it would be ''difficult'' to portray both Reggie and Ronnie - who were known as perpetrators of organised crime in the East End of London during the 1950s and 1960s - and it was something he'd never thought of doing before.

He said: ''All the plans are on the table. There's a lot of crossing the t's and dotting the i's, and there's a lot of shift and geography to work out.

''It would be difficult. It's quite technical and I'm a bit of an anorak.

''There's a physical transfer; we'd have to shoot one bit, go away come back and shoot it all again with another part. I've never dreamt of playing two people on the screen!''
