Christian Bale has given Batman successor Ben Affleck an important piece of advice.
Bale who played Bruce Wayne in Christopher Nolan's 'Dark Knight' trilogy - has told Ben to make sure he goes to the toilet before putting on the famous Batsuit ahead of his role in 'Batman vs Superman'.
The 39-year-old star told Access Hollywood: "The only thing I said to him is to make sure he can take a piss without anyone having to help him because it's a little bit humiliating - at least what I went through - when you have to have someone help you out of the costume in order to do that.
"That was my main piece of advice to him."
The actor thinks 41-year-old Ben will make the role "his own" and has nothing to worry about.
Christian added: "I wish him all the best, he's a very experienced actor and filmmaker.
"Our thing is finished, we always declared it was finished and it should be passed on to another actor - it will be again after him."
Henry Cavill will star alongside Ben in the film which is set to open in cinemas on July 27, 2015.
