Singer-turned-actor Jay Chou promoted the upcoming superhero movie "The Green Hornet" in Taipei on Monday, December 13, 2010.

Chou was the sole cast member appearing at the event, although the long-awaited film also features Hollywood stars Seth Rogen, Cameron Diaz and Christoph Waltz.

Talking about his Hollywood debut, Chou said he had nothing to worry about except that he had to speak English. The pan-Asian singing sensation plays Kato, the Green Hornet's Asian sidekick.

The film is slated for release in North America on January 14.
