It is being reported that actor Irrfan Khan hopes to make a return to acting with Shoojit Sircar's next film. The film is said to be a biopic about the life of Udham Singh. Mirror had reported on May 26, that Irrfan Khan had agreed to join the project. But, the film had to be put on hold after Irrfan Khan was diagnosed with a neuroendocrine tumor in March. Since then, he has been seeking treatment in London. But now, new reports suggest that the actor, who is currently undergoing chemotherapy, is responding well to the treatment. The same report also suggests that he is interested to return to acting as soon as possible.
