And after the iconic hero he could be moving to a sadistic businessman - Cavill is rumoured to be in the running to play Christian Grey in the Fifty Shades of Grey adaptation.
With the latest Man of Steel trailer giving audiences a taste of what to expect, just what else is there to know about the star?
1. Cavill was born on the island of Jersey, to Marianne - a secretary - and Colin - a stockbroker - as the fourth of five sons and with no sisters. He attended boarding school where he began to act in school plays and even directed one.
2. His first major film role was in The Count of Monte Cristo and from there he had various bit-parts in Stardust, Tristan + Isolde and Hellraiser: Hellworld. Hellraiser was almost hell for Cavill after being put in a harness to film a scene but then accidentally being left there while the crew had lunch. Let's hope something similar hasn't happened on Superman - that spandex doesn't look particularly comfortable.
3. Cavill is a patriotic guy and reckons that if he hadn't gone into acting, he'd be in the army or studying at uni. His chosen course? Egyptology - not too specific then! He's also fluent in French and knows some German and Italian, so if you're planning a European break be sure to bring him along!
4. Before his success in The Tudors, Henry auditioned for the role of Cedric Diggory in the fourth Harry Potter film, reaching the final two, but obviously he lost out to a pre-Twilight Robert Pattinson. Not one to be deterred, he auditioned for another teen franchise...
5. That teen franchise was Twilight - awkward much? He was actually author Stephenie Meyer's first choice to play the pale 17-year-old heartthrob, but producers deemed the then-25-year-old Cavill too old, instead offering him the part of Carlisle. As you will know, Pattinson won the part of Edward Cullen and we reckon Cavill might not be his biggest fan. As they say, acting is a young man's game!
6. Some of you may have noticed a certain passion of Cavill's, which is his penchant for leather jackets. We can't deny he does pull it off much better than we ever could. He's even said that he couldn't live without his favourite brown leather jacket. We reckon if you crept into his London home there would be a whole wardrobe dedicated to leather jackets and some industrial sized-hair products to help him achieve his slicked back Superman look.
8. His first big break came from being cast as Charles Brandon in the Showtime series The Tudors, starring alongside Jonathan Rhys Meyers. He lasted the full four series without being cut (or beheaded) and appeared in every single episode. It was from there that he was cast as the Man of Steel and became a well-known name in Hollywood, but for the right reasons this time.
9. However, becoming Superman was not plain sailing for the Jersey boy. He had to follow a strict 5,000 calories diet and undertake a rigorous regime at the gym for six months. This isn't the first time Cavill has auditioned for Superman either. He tried out for the iconic part in 2005 but lost out to Brandon Routh. Some may argue he had a lucky escape...
10. Cavill is the latest British actor to have been cast as an American superhero, following the likes of Andrew Garfield (Spider-Man) and Christian Bale (Batman). In preparation for his role, Cavill has been reading the Superman comic books, stating that he isn't going to watch any of the Superman films. Lucky him!
