The last two actors to portray Batman on the big screen were pretty stacked with the epitome of a superhero's frame.
Whether that was down to being pretty ripped or just thanks to a forgiving Batsuit, Christian Bale and Ben Affleck looked ready to take on any villain that got in their way.
However, don't expect the same when Robert Pattinson becomes the Batman.
After so many iterations in films, TV shows and comics, it seems like the former Twilight star isn't succumbing to pressure to bulk up his frame to fight baddies all over Gotham.
Despite being given a meal guide and a workout plan, the exercises he's been asked to do during isolation have been thrown to the wayside.
Speaking to GQ from his London home, the 34-year-old said: "I think if you're working out all the time, you're part of the problem.
"You set a precedent. No one was doing this in the '70s. Even James Dean - he wasn't exactly ripped."
His personal trainer, given to him by Warners Bros. Studios, gave Robert a Bosu ball and a weight to do some exercises, but he admits he's 'barely doing anything'.
He also admitted that during the Twilight days, there was an enormous pressure on him to have a certain type of body.
That pressure was only compounded, indirectly albeit, when he faced off against his on-screen rival, Taylor Lautner, who was absolutely shredded for the franchise.
Pattinson said: "The one time they told me to take my shirt off, I think they told me to put it back on again."
He is still sticking to his meal plan, which includes oatmeal with vanilla protein powder sprinkled on it, as well as tuna topped with tabasco.
It's a stark contrast to Christian Bale's attitude to playing the Caped Crusader in Batman Begins in 2005.
Admittedly, he had just finished filming The Machinist, where he ended up with a skeletal frame. To bounce back, he famously stacked on 45kgs in just six months.
"I had a lot of work to do because Batman [is] one of those parts you have to be in decent shape for," Bale told Femme Fatales.
"I ate like crazy, trying to put on pounds. I actually went way overboard. When I arrived in England, Chris Nolan looked at me in shock, saying, 'God, you're like some sort of grizzly bear!'
"It was not a very healthy thing to do; I could lift a lot of weights, but you asked me to run across the room, I'd be exhausted. So I started working out and doing a lot of running to bring my weight back down again."
It will be interesting to see how Robert Pattinson brings Batman to life in Matt Reeves' movie, which is slated for release on 21 October next year.Featured Image Credit: PA
