Sacha Baron Cohen is a hyperactive child: Helen Bonham Carter

Actress Helena Bonham Carter has compared her "Alice In Wonderland: Through The Looking Glass" co-star Sacha Baron Cohen to a "hyperactive child".
The pair previously co-starred in "Les Miserables" and most recently worked together on "Alice In Wonderland: Through The Looking Glass" and while Carter loves filming with Sacha, she admitted he can be exhausting, reported Female First.
Speaking to the Sydney Morning Herald, she said that Cohen, 44, is "totally unpredictable, like a hyperactive child sometimes [but]I'm not saying that, I'm not".
"He is very inventive, and he's fun, but... I'm pretty direct with him. Sometimes I think what Sacha doesn't appreciate is that he's just telling a story. The weight isn't always on his shoulders.

"A lot of the time it's just playing the scene, not inventing the scene. He comes from such an improvisational background. He can't but help improvise. It's interesting," she said.
Carter, 50, plays the Red Queen in the new movie, while Cohen portrays Time and she admitted filming on a huge sound stage against a green screen for CGI made things difficult.
"There was not much atmosphere. You know the problem is this room is huge, and you see everything. It's generalised lighting, so there's no sense of focus, there's no sense of, 'OK we're imagining'.
"On most sets you realise where the drama is. What's in front of, what's the imagined reality and what's off, but here there was no demarcation between me and Sacha trying to work in, and seeing absolutely every other member of the crew basically bored out of their head, I don't blame them for playing Sudoku. It was hard because it was completely sterile," she said.
