Shah Rukh Khan's double role in Om Shanti Om

If the buzz doing the rounds in the industry is to be believed, Farah Khan's eagerly awaited Om Shanti Om features Shah Rukh Khan in double role as Om and Om.

Unlike his other double role in Duplicate he won't be seen simultaneously on the screen in both the roles. SRK first plays a junior artiste from the 1970s who's bumped off by a jealous hero (Arjun Rampal). He's then re-born as Om.

While the theme of reincarnation and revenge is a direct tribute to Subhash Ghai's Karz, there are several other passages in Farah's feisty homage/spoof that pay tribute to or are take-offs on Bollywood stalwarts especially at those who mattered in the 'golden era' of 1970s.
