Robert Pattinson has expressed his delight at finally being able to put The Batman behind him - following a grueling three-year production that cost an estimated £100 million and a rumored falling out with the film's exacting director, Matt Reeves. He revealed that he almost quit.

The renowned actor known for his role in "The Harry Potter" franchise and "The Twilight" movie installments, also confessed that he was the type who would be "looking for the exit strategy before you've even started" something, adding that this picture "was one of the hardest things I've done in my life."

Not only did the actor, 35, injure his wrist during a stunt early in the production process, but he was also allegedly forced to reshoot sequences more than 50 times. His refusal to stay in shape during a six-month hiatus due to tight COVID-19 constraints also made things harder for him.

A source had told the Sun UK, "Matt will insist on doing scenes over and over again and get bogged down in the tiny details. Some­times it's like he doesn't know when to stop."

He also found the working climate quite isolating and depressing at times.

He reportedly provoked paranoia among team members upon his return and then testing positive for the dreaded coronavirus, struggled with loneliness while living in a tent across the nation, and had his interpretation of Batman's voice overridden after two weeks of filming.

At Wednesday's London screening of the superhero flick at Waterloo's BFI IMAX, the former Twilight actor said to The Sun: ''It's a relief. For (director) Matt Reeves, this is five years. I've been kind of working on this for three years."

Originally scheduled for release in 2018, R-Patz is believed to have been compensated $3 million (£2.24 million) to replace Ben Affleck, who had signed up to play in the eponymous role while directing and producing before experiencing personal setbacks.

Ben Affleck enrolled into treatment for alcohol addiction in 2018 following his divorce from his then-wife Jennifer Garner after a thirteen-year marriage.

Matt then cast Zoë Kravitz as "Catwoman," which made things harder for Pattinson as he found himself hoping for "cut!" to be yelled, before his perspiration fall into her mouth during strenuous scenes that led him to sweat heavily.

Moviegoers anticipating Robert's The Batman picture in theaters on March 4 should expect it to be the franchise's longest film yet at about three hours in length. According to The Hollywood Reporter, the highly anticipated comic book picture will last two hours and 55 minutes, including eight minutes of credits.
