NBC threw a press conference today to announce the Heroes World Tour that will include stops in Tokyo, Hong Kong, Singapore, Munich, Paris, London and New York. Fans will be able to follow the tour on nbc.com/heroesworldtour , which will include pictures and blogs.

The whole cast was on hand, including MILO VENTIMIGLIA (Peter Petrelli) and ADRIAN PASDAR (Nathan Petrelli.

Only notable absence: Leonard Roberts (DL).

“This is about the first season tour and the release for the first season DVD,” Creator and Executive Producer TIM KRING said explaining the actors’ presence without giving away the storyline for the show’s second season. Adrian Pasadar said: “On this show anything can happen. I am very happy to be up here today.”

“I took my wife to Paris and [Heroes] hasn’t appeared on TV there yet, and people were stopping me left and right, literally all over the place, because they are watching it on the Internet,” said GREG GRUNBERG, who plays Matt Parkman. He also revealed he was back to work, which led reporters to speculate that he survived taking four bullets to the chest in the season finale.

Season two of “Heroes” began production on Monday, and the cast was enthusiastic about being back to work, especially HAYDEN PANETTIERE, who stated, “It is amazing [to be back].”

Tim Kring clarified what is happening with “Heroes: Origins” spin-off. It will not feature cast members from the original show. He explained, “The idea is that these are the stories of other people. The show has posited the idea that this is happening all over the world. This is an opportunity for us to tell some other stories.”

The plan for “Heroes” is to run all 24 of its episodes, and then the six “Heroes: Origins” episodes will follow , which is a change from how the concept was introduced back in May.

The “Heroes” DVD and HD DVD ships August 28. It will include the never-aired 70 minute version of the pilot episode. [via ETOnline.com]
