Another detail about upcoming epic superhero team-up movie "Justice League Part One" has emerged. During an interview on "The Tonight Show Starring Jimmy Fallon", Henry Cavill confirmed that the movie, which would see him as Superman, would start pre-production in January 2016.

" 'Justice League', I think we start pre-production on that in January," Cavill told Jimmy Fallon. The actor said that he was currently in "off season" which means that he's not being involved in the filming of any Superman movie, noting that "Batman v Superman: Dawn of Justice" had already been in post-production.

As pre-production of "Justice League" approaches, Cavill has to prepare himself to get an awesome shape for his Superman role. He discussed his insane diet plan and said implicitly that the best cardio exercise for him was having sex.

There is no official cast announcement just yet, but Ben Affleck, Jason Momoa and Gal Gadot are expected to reprise their roles as Batman, Aquaman and Wonder Woman. Zack Snyder will direct the movie with a script by Chris Terrio and David S. Goyer. Produced by Dan Lin and Doug Mitchell, "Justice League" is scheduled to be released in North America on November 12, 2017.
