After his right forearm got pinned for nearly five days under a boulder during a climb in Utah in May, 2003, Ralston used a dull knife to amputate the limb.

Natalie Portman has branded her lesbian sex scene "extreme".

The 28-year-old actress - who has previously admitted she would consider embarking on a same-sex romance - insists there is nothing sexually compelling about the romp with Mila Kunis in new movie 'Black Swan'.

She said: "It's not raunchy - it's extreme".

The former child star - whose first big-screen role was in 'Leon' aged 13 - previously refused to strip-off the camera because she hadn't worked out her own sexual preferences.

Sean Penn's son will not face charges after being arrested.

Hopper - the Oscar-winning actor's 16-year-old son with estranged wife Robin Wright Penn - was taken into custody by the Los Angeles County Sheriff's department last week after officers visited his high school in Malibu and found drugs on him.

But it has now been reported the drugs were prescription medication in his name and no charges have been warranted.

Meanwhile, Robin - who filed for divorce from Sean in August - has revealed she moved her family away from Hollywood because she wanted her children to have a relatively normal upbringing.

Sandra Bullock thinks baring her bottom made her last film a hit.

'The Proposal' star said she is glad she stripped off for the romantic comedy - in which she starred opposite Ryan Reynolds - because the nude scenes were what helped make it a success.

Speaking about why the movie did well at the box office, Sandra, 45, said: "We had all the right people, the right elements in the right place. But to be honest I think nudity had a great deal to do with it. People liked it."
