Scottish star Gerard Butler is sweating hard to prepare for his role in Ralph Fiennes’ directorial debut, a film adaptation of playwright William Shakespeare’s tragedy Coriolanus. The 40-year-old actor, currently promoting his film The Bounty Hunter with actress Jennifer Aniston, is heading to Belgrade to start shooting the movie, in which he plays rebel leader Tullus Aufidius, reports Daily Mail.

“Tullus is totally fearless and I’m getting in shape and having fight training. War’s not supposed to be fun, but I’m looking forward to making the film with Ralph,” Butler said. The plot revolves around Roman hero Coriolanus, played by Fiennes, who is banished from the city only to return with its sworn enemy in an effort to avenge his honour.“Tullus and Coriolanus have shed blood on the battlefield and there’s an admiration they have for each other,” Butler said.
