The most challenging and exciting aspect of ''Bhoot'' was the ship. So getting the ship to look and feel authentic was the key. "We spent a lot of time on research, referencing and scouting real ships to get the right vibe. Anybody who hasn''t worked or been on a cargo ship does not know what it''s like to experience the enormous size and the claustrophobia. I wanted everyone who saw this film to actually feel like they are present and trapped there," he added.
