Matt Damon Bourne again for new movie
Alicia Vikander said Matt Damon left her constantly "on edge" on the set of Jason Bourne - because she was waiting for him to prank her.
The Swedish actress finally looked relaxed as she walked the red carpet for the film's European premiere in London's Leicester Square, alongside Damon, who reprises the role of former CIA assassin Bourne for the fourth time.
Despite being the "new girl", Vikander said the cast "made it feel like you were entering a family".
She added: "They love a joke and prank on set. They never got me, but I think Matt's going to come for me at some point."
Damon, renowned for playing pranks on pals George Clooney and Ben Affleck, said he "took it easy on Alicia" because they were so lucky to have secured her. The film is released in cinemas on July 27.
