The director of Zack Snyder admitted that the new movie was not intended as a standalone project.
"We didn't design the movie like Batman [as a trilogy] but I don't think anybody would say you design a Superman movie as a one-off," he explained.
But the last Superman movie - 2006's Superman Returns was also planned to spawn further adventures - until it had a disappointing performance at the box office.
However the market for comic book movies has grown rapidly in recent years and Snyder is already reported to have been signed-up to direct a Justice League ensemble movie based on Superman and other DC Comics heroes.
In other Man Of Steel news, Michael Shannon also spoke to Empire magazine - and discussed his approach to playing iconic villain General Zod.
He claimed that he deliberately took a different tack to Terence Stamp's portrayal of the same character in the Christopher Reeve Superman movies.
"As much as I love what Terence Stamp did in that movie, it was kind of opaque," he said.
"It was impossible to have any empathy with him, it was pure malice.
"We wanted to break down that wall a little bit, so the audience might think, 'Yeah, I know what he's going through'. It's not better or worse, it's just different."
