Sacha scares child co-star on Hugo
Hugo star Asa Butterfield has admitted he was intimidated by Sacha Baron Cohen while working with him on the 3D adventure.
The 14-year-old star of Martin Scorsese's new film was expecting the Ali G comedian to be fun, but revealed it was "weird" when he stayed in character as the scary Station Inspector all the time.
Asa said: "When I heard he was going to be playing it, I thought he would be really jokey and sort of ... Borat. But he was very serious on set and everyone had to call him by his character name and he would even stay in role when we weren't filming.
"I was a bit intimidated by him because he's quite an imposing figure, but we had a great time chasing after each other."
But Asa did get on with his 14-year-old co-star Chloe Moretz, who plays Hugo's friend Isabelle, and the pair have become friends.
He revealed: "We bonded straight away and we hung out a lot. We both like very teenagerish things so when we weren't filming, we'd often play table tennis in my room or play on the PS3."
Asa also confessed: "There were lots of pranks on set. We tied up the first AD [assistant director] with some tape to a wheelie chair and pushed him down the hallway."
Chloe added: "And then we pushed him around and he videoed it and we kept running his legs into pipes and stuff."
She joked: "It was really not OK!"
