In Warner Bros.' upcoming "The Batman" film, Joe Manganiello will suit up as the mercenary Deathstroke to take on Ben Affleck's Dark Knight. A role like Deathstroke involves a lot of training and preparation, which Manganiello has already started with a personal trainer. The actor shared some of his training regimen with Chef Robert Irvine.

When asked how his training was going, Manganiello replied, "I’ve started. My trainer and I have started putting together some workouts that are specific to the character and how I want the character to move. It’s an incredibly athletic role so all of the training is very functional. I’ve also started Kung fu and chi gung training, and I’ve also started working with katanas."

The "True Blood" alum was also asked if he feels pretty good working with katanas. With confidence, he replied, "I’m gonna be ready."

Manganiello recently discussed his prowess with katanas during an appearance on the Dragon Talk podcast. "I’m somebody that likes to start preparing way ahead of time,” said Manganiello. “So I’ve read almost all the comic books involving him. Just to get the information out of them. Some of them are useful. Some of them are not going to be useful. Because ultimately the script — that’s my text. I have to play that."

"The Batman" will be directed by Matt Reeves, with Ben Affleck remaining on board to co-write the film alongside DC Entertainment President and CCO Geoff Johns. Affleck will star as the Dark Knight alongside Jeremy Irons’ Alfred Pennyworth, J.K. Simmons as Commissioner Gordon and franchise newcomer Joe Manganiello as Deathstroke.
