Former Batman portrayer Christian Bale has even more advice for Ben Affleck as the latter takes on the iconic role in Batman v Superman: Dawn of Justice.

Iconic Batman Character Will Reportedly Be Dead in 'Batman v Superman'

Bale, who is currently promoting his new film Exodus: Gods and Kings, reportedly gave a few pieces of advice to Affleck before he was slated to don the cape and cowl.

"The first one was, 'Be able to take a piss by yourself,' " Bale said, according to a new report by the New York Daily News. "I found it to be ridiculously unheroic between takes when I said, 'Excuse me, I need to pee, could somebody undo me please?'"

He also suggested that Affleck make sure the costume designer made a comfortable cowl.

"[It] took three people 20 minutes with tools in order to take that cowl off (my) head," Bale admitted.

Now that he has passed the role on to Affleck, Bale may be feeling a little weird that it is happening so soon.

"The baton has been passed, that's the nature of Batman," Bale said. "Of course, it was passed a lot quicker than I expected, but I completely understand."

Affleck leads an all star cast that includes Henry Cavill as Superman/Clark Kent, Gal Gadot as Wonder Woman, Amy Adams as Lois Lane, Jesse Eisenberg as Lex Luthor, Perry White as Laurence Fishburne, Diane Lane as Martha Kent and Jeremy Irons as Alfred, butler to Bruce Wayne.

Batman v Superman: Dawn of Justice is slated to open in theaters on March 25, 2016.
