Shah Rukh Khan's 'Ra.One' is already loaded with attractive superhero storyline, high defying action sequences, sizzling hottie Kareena Kapoor, international pop singer Akon... As if that was not enough, the makers have now gone ahead to make it more exciting package.

News in the town of late is that the production Red Chillies Entertainment has signed on Priyanka Chopra and Sanjay Dutt for special appearances in 'Ra.One'. Wow, two such impressive personalities, aren't they? Priyanka, who already co-starred with SRK in 'Don', now 'Don 2' and played cameos in 'Billu Barber' and 'Om Shanti Om', is an ardent fan of the Badshah and when she heard the 'Ra.One' offer Priyanka immediately gave her consent. The 'Desi Gal' is said to feature in a long-drawn romantic sequence in the movie and will also get to perform a lot of stunts as well. As 'Ra.One' is essentially a fantasy film, this song is considered as a sweet dream sequence, sources said.

Coming to Sanjay Dutt's involvement..... Sources revealed that Shah Rukh looks up to Dutt as his elder brother and he was quite gung ho about the latter's macho avatar in 'Agneepath' remake. SRK was so impressed with Sanjay's beefy image that he felt that they should bring him on board to do an action cameo.

Cool, 'Ra.One' is surely going great guns, we say.... Indeed it's shaping up to be something to watch out...
