Cavill, 30, said he knew that he will be compared with the previous actors in the superhero series, which is celebrating the 75th birth anniversary of DC comics' Superman.
"There is a pressure that I will be compared. Christopher Reeve was Superman as far as live action goes. I have done my job now and I can't change people's minds. But I just hope we tell a great version of the story.
Directed by Zack Synder and produced by Warner Bros and Legendary Pictures, 'Man of Steel' releases tomorrow.
The British actor said that he had to undergo a gruelling physical training for seven months to get in shape for his role as Clark Kent and his superhero alter-ego.
"The biggest challenge was the probably physical side of it. Transforming my body to sort of look like that. It took about 5 months to get to a certain state and another two to get to the shirtless state. It was a lot of hard work," he added.
"The suit did not make me more relatable. It was the storyline. The suit itself was a Kryptonian thing and an alien thing and so less relatable than the previous suit which was a strong man thing. The suit wasn't the vehicle for that. There was more storyline," he said.
