Inside the issue - which is available for just £1.99 on your iPad - Farrell says that he's always enjoyed his co-star's work.
“Good luck to him," he says. "I think he'll do a great job. As an actor, I don't know that I know anyone that's improved as much as he has. That sounds like a shit thing to say.
"In Argo , it was such a controlled performance, I think he'll kill as Batman, I hope he does and shuts the naysayers up."
Farrell's next film, A New York Winter's Tale, o pens in the UK on 21 February 2014.
