Director Kamaleshwar Mukherjee mentioned Chander Pahar as his "dream project". But he even compared the project to a "double-edged sword" as he realised the challenges while looking for locations in South Africa for a month. When Shree Venkatesh Films agreed to produce the film, they wanted a big star in the lead role. As a result, it was filnally decided that actor Dev will be going to play the role of Shankar, the protagonist.
A source close to the Chander Pahar unit revealed that the production house wanted a big star to play Shankar, the adventurer protagonist. At the beginning, Dev and Parambrata's names had come up. However, Kamaleshwar Mukherjee later said that Dev was in his mind and also in the producer’s (Shree Venkatesh Films) mind from the beginning. They needed an athletic body for the role of Shankar because in the book it is mentioned that Shankar was into boxing and he knew horse riding and swimming. Dev is learning horse riding and he is also good in action scenes. Therefore, finally he was chosen to be cast as Shankar, instead of Parambrata. Dev also agreed to do that as he was brought the offer. But he was asked to lose weight because in the latter part of the film, Shankar fights with lions, walks through jungles and mountains, and almost starves.
Though the production house has yet not released any official poster of Chander Pahar, a large number of unofficial posters have been designed by graphic designers and promoted in social networking sites such as Facebook and Twitter, featuring only Dev in the foreground and a background somewhat similar to the official cover art of the novel. It was later found out that some of these were unofficial versions and morphed screenshots from the 2011 Australian movie The Hunter. (To compare : Morphed version and Original
on 24th May 2013, the first look of Dev as Sankar was released by the production house, it was selected out of five different looks for Sankar in the film.
According to the latest news, the budget of Chander Pahar is going to be the highest till date in Bengali Cinema. The film will be produced by Shree Venkatesh Films and will be shot on locations in Africa. The film is reportedly being made with a budget of nearly 35 crore INR, which is roughly equal to 6.27 million USD - thus making it one of the most expensive movies ever made in Bengali film industry.

For Shree Venkatesh Films, Chander Pahar marks the latest in a series of adventure films. According to the Times of India, it will be a high budget film and have computer graphics that no one has seen before in a Bengali film.
Other than these sequences, there are other scenes regarding which the crew members are worried. These are the scenes which ill be shot at the Kalahari Desert. The production team of Chander Pahar said that the place in the Kalahari Desert where the film will be shot is nearly 300 kilometers from their hotel and the team has to cover 600 kilometers regularly during the shoot. "The most dangerous thing is that we have to return in the presence of daylight. Otherwise, we cannot return once there is darkness over the red desert. The place is so impassable that there is no sign of roads. We will get lost. Over that, the day temperature there is 50 degrees. And the night temperature is 4 degrees", said Kamaleshwar Mukherjee. Other than the Kalahari Desert, the film will also feature actor Dev in a rock climbing sequence. This sequence will be shot at such a mountain that if one falls down from there, he will be 500 feet down straight. There is also a sequence of Dev inside an old cave with a Python.

Other places where the filming will take place include the jungles of Mpumalanga, Elands River valley, Blyde River Canyon, Kruger National Park, mountains of Drakensberg and the Kalahari Desert. The film will also be shot in Kenya and Uganda, besides South Africa.
Some special scenes of the film will be made with the help of computer graphics. The most notable of these are the eruption of the volcano and the sequence featuring the monster called Bunyip.
