Ajay Devgn and Tabu starrer "Drishyam" received average occupancy on its first day at the domestic box office. The film recorded eighth highest opening day box office collection this year.

"Drishyam" had poor occupancy in the morning shows, but it showed growth in the evening shows. The occupancy rate increased in the evening shows due to rave reviews, which resulted in Rs 8.5 crore first day income.

The opening day box office collection of "Drishyam" is eighth highest this year after "Bajrangi Bhaijaan", "ABCD 2", "Gabbar Is Back", "Dil Dhadakne Do", "Roy", "Baby" and "Tanu Weds Manu Returns".

The opening weekend box office collection of "Drishyam" is expected to be good as the word of mouth is positive.

Meanwhile, the director of the film Nishikant Kamat said that he is more worried about people's appreciation than the business of the film.

"Monetary things have never mattered to me. I have not thought how much collection my films will make while making them, but I've always felt the need to make a credible film. I've always worried about people's appreciation," he told IANS.

"My biggest fear has been boredom. I get bored of one type of a film very fast. If you see all my films, whether its 'Mumbai Meri Jaan' about social awareness, hardcore police-based film like 'Force', 'Rowdy Rathore' type film 'Lai Bhaari' or a suspense thriller like 'Drishyam', they all have been of different genres.

"I do this because then there is a challenge and you know that you are doing something which you have not done in the past," he added.
