Earlier Ranbir and Alia along with Ayan had flown down to London for a quick script-reading session for this film which is rumoured to be a trilogy.
Dragon is a fantasy-based film set in contemporary times. Ranbir plays a young boy with some form of super powers. A source further added, "His character has shades of grey and his powers include emitting fire from his palms. He has to practise limb coordination and is training with international experts."
The actor will be learning different techniques for the high octane stunts and will undergo special workshops to get the physical nuances of his character right.
