Raj, Vijay and Rahul
Some names catch on in such a big way that they refuse to remain restricted to any particular filmmaker.
Amitabh Bachchan is synonymous with Vijay, a name so popular it could well figure on his passport. From Zanjeer and Deewar to Shahenshah and Agneepath, it's Vijay-path all the way.
Though Shah Rukh Khan made history as Raj Malhotra in Dilwale Dulhania Le Jayenge, filmmakers love to call him Rahul. Be it Darr, Yess Boss, Dil To Pagal Hai, Kuch Kuch Hota Hai or K3G, it's always, 'Rahul, naam to suna hoga?'
And there are others, like the charismatic Raj Kapoor, who was simply known as 'Raj' in some of his memorable movies like Shree 420, Awaara, Anari, Aah, Dastaan and Bewafa.
