"This is probably the first time in Indian cinema that films of superstars from different languages are going to vie for the top spot at the box office. It's tough to predict the winner because expectations are riding high on all the three films," trade analyst Trinath, told IANS.
The tough competition will especially be tough in the overseas market, he said.
"'Chennai Express' will have a wide overseas release. I was told it's being released in countries like Morocco, Israel and even Germany, while 'Thalaivaa' and 'Attarintiki Daaredhi' will predominantly target countries such as the US, Britain and Australia," he added.
But, the first week of August will also see the release of Hollywood biggies such as Disney's "Planes", Neill Blompamp's "Elysium" and Thor Freudenthal's "Percy Jackson: Sea of Monsters".
"It's going to be neck-to-neck competition for these films. 'Chennai Express' has already got maximum number of screens in most countries. Pawan Kalyan has great market in the US and his films usually have good openings here," an international distributor of Indian films, told IANS.
Pawan Kalyan's "Gabbar Singh", Telugu remake of "Dabangg", raked in over $1 million in the US upon release in its first week.
Trinath believes it's the box office opening that will make the difference for the three big-ticket films.
