Oscar nominated Djimon Hounsou (Blood Diamond) and rising star Alexis Knapp (Pitch Perfect) are attached to star in Main Street Films, MK Create and the Kojo Group's action adventure One, written and directed by Murali K. Thalluri (2:37). The announcement came today by Main Street Films' Chairman Craig Chang and President Harrison Kordestani, who are executive producing the film.

Main Street Films is co-producing and co-financing the film with Thalluri for MK Create and Kent Smith for the Kojo Group (Julie Bertuccelli's The Tree starring Charlotte Gainsbourg). Greig Buckle (Lord of War, Chronicle) of Enigma Pictures is serving as co-producer. This is the first film to be produced under the South African and Australian co-production treaty launched in 2011.

Kathy Morgan International is handling worldwide sales.

Sammy Sheik (Lone Survivor, Transformers: Dark of the Moon) has also joined the cast in a supporting role. Casting is still ongoing and more names will be announced soon.

To be lensed by Lance Gewer (Oscar winning Tsotsi), production is scheduled to begin in 2014 on location in Johannesburg and Cape Town, South Africa. One is set in a post-apocalyptic world after a virus has wiped out 99% of humanity, leaving those who have survived divided into separate racial groups all fighting each other to find a cure to help their own. When Ava's (Knapp) house is raided by Junaid soldiers, a group of racial minorities who have banded together, she is captured and sold to a medical research facility searching for a cure. When it becomes evident that Ava is immune to the virus she becomes not only the most valuable person on the planet, but the hope of the world.

Here's what Craig Chang had to say about the project.

"Murali K. Thalluri and Kent Smith are putting together a strong cast led by Djimon Hounsou, who always delivers exceptional performances, and rising star Alexis Knapp for this powerful and evocative film."

Harrison Kordestani also added his own statement.

"Taking the lead in this multi-layered film will give Alexis the opportunity to show off her talent as a dynamic actress and we are delighted to be partnering with Murali and Kent on this gripping film."

Murali K. Thalluri also released his own statement.

"We've assembled a very talented cast and crew who have elevated the vision beyond what I alone could imagine. This team is greater than the sum of its parts. I'm excited."

Kent Smith had this to say in his statement.

"Kojo and I are very excited to be involved in this unique project. Murali and I had a great partnership both critically and commercially on 2:37, and we look forward taking it to the next level with One."
