Benedict was the victim of a practical joke

Benedict Cumberbatch failed to use Sherlock-like logic when he started filming sci-fi flick Star Trek Into Darkness.

The actor, who plays villain John Harrison in the movie, fell for an elaborate prank thought up by cast members and crew.

‘I was totally oblivious to a joke that was being hatched against me until it was way too late to do anything about it,’ says Benedict, 36.

‘We filmed scenes at a place called the National Ignition Facility in California, this incredibly hi-tech establishment full of state-of-the-art technology designed – among other things – to find alternative sources of energy.

‘Everybody, from the electricians right through to the actors, convinced me that I needed to slap on something called Neutron Cream in order to protect myself from potentially harmful lasers.’

And the joke didn’t stop there – the tricksters even persuaded Benedict to use a very unusual application method.

‘I fell hook, line and sinker for it, as I did for the notion that a) I had to put it on in little blobs all over my face, and b) that I then had to jump up and down to nullify the threat of the lasers,’ the actor tells Weekend Magazine.

‘I did all of this before I realised everybody was laughing and applauding. I’d been had, good and proper.’
