Films on board an international cruise have not proved too lucky for Ajay Devgn (his directorial debut U Me Aur Hum whose first-half was shot on a luxury cruiser, bombed) and Aamir Khan (one of his rare failures in recent times Indra Kumar's Mann was shot on an oceanic trip).

But Akshay Kumar thinks cruisers are too cool. His Ajnabee was shot on a luxury cruiser. Now there's a cruise interlude in Anees Bazmee's Thank You.

Says a source, "An entire chase sequence on a luxury cruiser was devised. A chase conventionally meant to be on the road was shifted to the sea. And the entire team left for the cruise. Because of the shift from land to sea there were endless hitches, glitches and obstacles."

Director Anees Bazmee who's just back from the ocean-liner nightmare doesn't deny the problems. "Yes, it was very tough. We shot for four days on a cruise from Bangkok to Phuket. The unit was stationed on board the ship. We were on the ship and shooting in the water like a proper location. The situation was that Akshay and Sonam were on board and they were being chased on a motorboat by Bobby Deol, Irrfan Khan and Suneil Shetty. So we had to get both the ocean-liner and the motorboat in camera range."

The chase sequence had to be shot aerially. Says Anees, "We had to shoot the entire sequence from a helicopter. It was complicated and costly."

But if the film clicks then Akshay would have the last laugh, right?
