Tom Hiddleston says that Benedict Cumberbatch will not tell which villain he is set to play in the new Star Trek movie.
It was revealed last week that Cumberbatch will be joining the cast of the J.J. Abrams movie but despite being hounded by Hiddleston he has remained tight lipped.
Speaking to the Press Association the actor said: "Ben hasn't told me who he's playing in Star Trek, so he's keeping very tight-lipped.
"I was badgering him all day, we were doing the rounds together and he said, 'No, won't'.
The pair starred together in the Steven Spielberg directed movie War Horse, which is currently top of the UK box office.
Hiddleston will be back on the big screen this summer as he reprises the role of Loki in The Avengers.
He is also set to reprise that role in a second Thor movie, which is due to begin filming this summer.
