when it is screened in Cannes

Are you sure that it was going to be shown there? I thought so too, since the actors and director were there, but I can't find anything about a screening of it on the Cannes website. "Raavan" actors might have been promoting it and the trailer might have screened there as well... but I could be wrong.

I was a bit absent-minded. I've been waiting for reviews for this; waiting on the computer/internet patiently 18th and 19th, google-ing keywords "Raavan" and "reviews" but there was NOTHING. I looked up the official "Raavan" website and it said released on the 18th June. I was wondering "When on earth are the first reviews coming out? It's already past the 18th. It's an eagerly anticipated film - surely reviews should be out now!?!?". It dawned on me MUCH LATER that this is not the month of June, that we are still in May!

It's not being screened at Cannes, just promoted!
