Simon Pegg played a trick on Benedict Cumberbatch during filming of Star Trek Into Darkness – by convincing him that he was in danger from radiation on the set. Pegg told Chris Pine – who plays Captain James T Kirk – that the cast were at risk, and the rumour spread. He told the Sun: "I don't like seeing people get embarrassed. But we were filming in a nuclear facility and one day I said that Chris needed neutron cream – otherwise he'd get sunburn. He said, 'What?' And I said, 'Yeah, you'll get a rash from ambient radiation in the air.' From there the trick spread to other cast members. Finally, we got Benedict. He had this speech and he kept fucking it up. Afterwards he said, 'Guys, I'm ever so sorry - I've got a real headache. I think the ions were getting to me.' He was so convinced."
