LexCorp tower in Man of Steel trailer

Fans spy the headquarters of Lex Luthor in the sneak peak of the new Superman film

With the latest trailer for Zack Snyder's Superman reboot 'Man of Steel' having been viewed over three million times already, eagle-eyed fans have now taken it to pieces frame-by-frame.

One of the most intruiging findings is that a tower in Metropolis appears to be emblazoned with the logo for Lex Luthor's conglomerate LexCorp.

It's got fans supremely excited to know that Luthor exists in Snyder's rebooted world, and that he's already weilding some power.

Whether he will make any kind of small appearance in the first film is not yet known, but as some blogs are pointing out, producer Warner Bros has a history of introducing the lead villain in its superhero franchises in the second film – as they did with the Joker in 'The Dark Knight'.

This in turn could suggest that the mooted 'Man of Steel' sequel will find Superman up against his true arch nemesis, the supervillain industrialist Luthor.

Past Luthors have been played by actors including Gene Hackman and in Bryan Singer's 'Superman Returns', Kevin Spacey.

The new trailer is the first to show Snyder's vision in any detail, and has been overwhelmingly well-received so far.

The film stars British actor Henry Cavill in the role of Superman, Amy Adams as Lois Lane, Russell Crowe as Jor-El, Kevin Costner and Diane Lane as the Kents, Laureance Fishburne as Perry White and Michael Shannon as General Zod.

It's due out on June 14.
