He is set to portray superhero Ray Garrison aka Bloodshot, a super-powered soldier who is the first character to feature in the Valiant Cinematic Universe.
And Vin Diesel was seen hard at work on set of the hotly-anticipated blockbuster, as he shot scenes where he got hot and heavy with his co-star Talulah Riley in Kalk Bay, Cape Town.
Filming sweet kissing scenes on Wednesday, ahead of the film wrapping on Friday, the actor, 51, and actress, 33, were in the throes of their on-screen romance as they immersed themselves in their roles.
Vin looked unexpectedly casual despite playing a superhero, as he donned a crisp white shirt over his hunky torso.
He teamed up his top with a pair of loose-fitting denim jeans, while he offset his whole ensemble with a pair of beige Timberland boots.
Talulah matched her co-star by wearing a sleeveless white midi-dress, while she boosted her height in chic grey heels.
The Westworld star wore her blonde locks in a messy bun, and had brushed on a natural palette of make-up to highlight her pretty features.
Vin's character is a former soldier who gains the power to regenerate and shape shift because of nanocomputers injected into his blood.
Having had his memory wiped on multiple occasions, the comics see Angelo aka Bloodshot become desperate to know who he really is, and to get his revenge on those that did this to him.
Talulah, meanwhile, plays Gina DeCarlo, the daughter of mob boss Don Cianelli and Angelo's girlfriend.
Speaking to Comicbook.com about the film, Vin gushed: 'You're watching something and you're going...I guess I expected that we would finally get here in the superhero universe, but I can't believe we're here.
'Dave Wilson, who's directing it. Guy Pierce, who's in it is insane. We just have a great cast.'
He then added: 'Sony, you know that Sony is finally going to lead the charge in the superhero movies of the future because they're incorporating a part of reality and incorporating issues that exist in society and embedding them into a quote-unquote superhero movie. It's just awesome.'
