Hrithik-Preity Zinta: Science 'fizzion'!

they can create magic on screen together. but right now, they're planning to handle extra-terrestrial beings. no, they're not on a trip to the moon and beyond. they're merely doing a film together which is allegedly based on steven spielberg's 'e.t.' titled 'koi mil gaya', the film is being produced by rakesh roshan, who earlier gave the super-duper hit 'kaho na...' which catapulted beta hrithik into the stratosphere.guess dad roshan has every intention going beyond the 'stratosphere'. why else would he pick 'science fiction' as the subject?
