Bollywood superstar Shah Rukh Khan's latest superhero film Ra.One had its London premiere at the famous O2 arena here last night and judging from the viewers reaction the Indian science fiction seemed to be a "hit". Shah Rukh's stellar performance is a major attraction of the film but co-star Kareena Kapoor and Armaan Varma have also acted brilliantly. Thousands of fans, after hours of waiting, went wild as Shah Rukh, wife and the film producer Gauri Khan, Kareena and actor Arjun Rampal walked the red carpet. They cheered the stars repeatedly and sought their autographs and posed for photographs.

Replying to queries, SRK said though the film has been made at international standards, "it's soul is pure desi. It has singing and dancing." Shekhar (Shahrukh Khan) is a graphics designer, who believes in simple living and high thinking. But his son (Armaan Varma) mistakes him to be a coward. Shahrukh tries every trick to win his love. In a bid to prove himself, Shekhar designs a game.

However, all hell breaks loose when the game starts playing them. What happens next is quite mind boggling which keeps the viewers glued to the seats. Shahrukh has delivered superb performance in both roles like Shekhar and G.One and he emerges as the showman. Kareena also impressed the audience with her witty dialogue and fine acting. Arjun and Armaan have also done excellent acting.

The works of technical department are absolutely superb. Vishal-Shekhar's music is superb. Their background score is equally electrifying and their composition of songs like 'Chammak Chhallo', 'Dildaara' and 'Raftarein' are winners. The visual effects of Ra.One are another highlight of the film and the stunning chase, action scenes and train sequence hold the audience spell-bound. The film is being released today in about 5,000 screens worldwide. After the late night premiere at the O2 arena, SRK, Gauri, Kareena, Arjun and others associated with the film moved to Court House hotel in central London owned by leading NRI hotelier Joginder Sangar and partied till around 3 am.
