The sequel to Superman Returns should hit theaters in three years, according to Warner Bros. Pictures President Alan Horn.
Horn told the Los Angeles Times that he expects Singer's first Superman film will eventually gross about $400 million worldwide, more than last year's hit Batman Begins, but at least $100 million short of his expectations.
"I thought it was a very successful movie, but I think it should have done $500 million worldwide," Horn said. "We should have had perhaps a little more action to satisfy the young male crowd."
He says the studio is nonetheless planning on a sequel in the summer of 2009.

Meanwhile, Hollywood Reporter did an article comparing Superman Returns to X-Men: the Last Stand and had this to say about Singer's plans for the sequel:
"While some 'Superman Returns' viewers objected to the addition of an illegitimate child of Lois Lane and Superman (which never appeared in any of the comic books), Singer intends to proceed with that story arc. 'There's a lot of room to go with that character and his upbringing and human background and Krypton heritage,' he says. 'He's the genetic material of both parents. Superman doesn't have that. It's hard to write for Superman. He's a tough character to create insurmountable obstacles for. This one is unique and insurmountable.' For the sequel, Singer will be able to expand and play around with what he's introduced, and 'bring in more of the energy' of the contemporary comics, he promised," according to the Hollywood Reporter.
