"G.One stands for the good one & sustainer of life. To protect life he is ready to put his own [on] the line. Hope u all like him....will show soon," Khan tweeted on May 31.
The 44-year-old actor, who has had to loose a lot of weight for his super-hero role, joked that he feels G.One could well stand for Gaunt One.
"After losing so much weight i feel g stands for the gaunt one," he tweeted.
The name of the film - Ra.One - is short for Random Access Version 1. The film targets kids and is about a superhero who can freeze electricity.
Khan plays a Miami based software engineer named Shekhar, who as a video-game hero takes on his self-created techno-monster Ra One.
The film, set in London, additionally stars Kareena Kapoor and Sahana Goswami.
Kareena plays lead in the film, opposite Khan, as a young mother of an eight-year old. When he falls in love with Kareena, Khan imagines her as one of the characters.
Sahana's character in the film helps out Shah Rukh's when a gaming character causes problems for him.
"Ra.One is a very ambitious project. It's a film that kids will enjoy for sure. It's not only for kids but the idea is also to bring action to a different level. It's hugely experimental," says Arjun Rampal who plays villain in the film.
American singer Akon recorded a song for the film in Mumbai.
Filming started in India on March 24 and is close to wrapping up. Next, a schedule is planned in London, starting in the first week of July.
The film will have state-of-the-art special effects provided by Hollywood technicians.
Shahrukh has not been much of a consistent visitor to the IIFA. 





The buck on My Name is Khan just does not seem to stop. Soon after the US release of the much celebrated film it has not found its way to the Google headquarters. On Monday the film was screened at the office as a part of a regular seminar initiative by Google.
