The actor worked with performance capture expert Andy Serkis and top motion coach Terry Notary as he tried to perfect the character Koba in the film, and he admits playing a violent ape was a lot more challenging than he thought it would be.

"I got this fracture thing called an ulna fracture, which is when your tendons are stronger than your bone," Toby tells Entertainment Weekly.

"The tendons literally pull the bone apart at its head, and then I got two dislocations in one fell swoop. But I did it to myself."

"Stupidly, I figured anyone could do a monkey...," Kebbell adds. "Little did I know that by week two of working with Terry Notary, I would be barely able to walk after crouching for 10 hours a day."

The actor returned to the performance capture world to take on the character of orc chieftain Durotan in the new Warcraft movie and on set he realised just how much he'd learned from Lord of the Rings and King Kong star Serkis.

"It's like working with a grand master," he told the publication. "I had an apprenticeship (on Dawn of the Planet of the Apes set). He's not a hands-on, 'This is how you do this' teacher. It's there if you're smart enough to pick it up."

He certainly had more fun aping Serkis on set than he did making the Fantastic Four, fearing the 2015 film flop had ruined his career.

The actor, who played Doctor Doom in the movie, accepts the remake was not what it could have been, and although he was disappointed when the summer flop was savaged by critics and fans alike, he wasn't surprised.

"As an actor, you're conscious that your career is at stake with each job, especially on these larger productions," he explained. "A film like that comes out, and I'm being sent maybe four scripts in a week, and those scripts go to zero when it doesn't come out successful (sic)."
