'Star Trek' legend Leonard Nimoy is to star in 'Lost' creator JJ Abrams' new 'Star Trek' film.

Nimoy and 'Heroes' star Zachary Quinto will both play Mr Spock in the new film, which is believed to tell the story of how Captain James T Kirk and Mr Spock first met.

Both actors joined JJ Abrams at the San Diego Comic-Con International convention as he made the announcement.

The 11th 'Star Trek' film is due in cinemas in December 2008.
