This could have been the Clash of the Titans with the presence of supposed rivals Shah Rukh Khan and Aamir Khan at the London premiere of Abhishek Bachchan and Aishwarya Rai starrer "Raavan" Wednesday, if the latter had not missed the event for his mother.

While Shah Rukh got an invitation both from Abhishek and his megastar father Amitabh, Aamir was invited by the Big B himself.

"Amitji invited me for the premiere of 'Raavan' in London when I was there. But I had to come here for my mother's birthday on June 13 and go to Pune to be with her. However, I wish the movie gets success and all my best wishes to Abhishek and Aishwarya, " said Aamir.

A bilingual, "Raavan" is releasing Friday worldwide.
