SAN DIEGO (AP) - There are lots of people dressed like Superman at Comic-Con, but the real guy - or at least the actor playing him in the latest Superman film - made a surprise appearance at the fan festival.

"Man of Steel" director Zack Snyder presented new footage from the film on Saturday and introduced star Henry Cavill to an audience of more than 6,000 fans.

The British actor said "it's a dream come true" to play the iconic superhero, but confessed "it is pretty intense."

The footage showed Clark Kent as a boy and Cavill in his super suit, along with glimpses of co-stars Amy Adams and Russell Crowe.

Snyder said the film will make Superman more relatable than previous depictions that showed him as "a big blue Boy Scout up on the throne and you can't really touch him."

"The big challenge, of course, is if you can make people feel, `What would you do it you were Superman?
