"Pink", a courtroom drama, starring Amitabh Bachchan, Taapsee Pannu, Kirti Kulhari, Andrea Tariang, Angad Bedi among others, was a critical and commercial success.
Aniruddha says he is currently working with two ideas and is not sure which one will become a film first.
"I am working on a Bengali subject and a Hindi film at the same time. I don't know which will happen first. It's too soon to tell what the films will be about. But I have ideas for films in both the languages as of now," Aniruddha told PTI.
When asked if Bollywood producers have started to approach him after "Pink" he says, "I did get offers before 'Pink' but Shoojit was a friend. So he held my hands and said 'let's do this together'. The credit goes to him. It's 100 per cent my film, it's 100 per cent his film. Both of us made it happen."

The director says things have changed post his Hindi debut but he wants to approach a film the same old way- to make it only when it appeals to him.
The director was speaking at a session at the ongoing 47th edition of International Film Festival of India (IFFI).
Aniruddha says for his debut film in Bengali, nobody was willing to invest money into the project, which ultimately bagged a National award.
The film explored the relationships of two married couples, and the impact and consequences of their relationships.
"We sold it properly, the film ran for 100 days and also got a national award. It is a very difficult task to get Rs 1 crore or 80 lacs," he added.
Joining him on the panel were filmmaker Sudhir Mishra and Raam Reddy.
"We need festivals because it is a place where networking happens. By that I don't mean money networking but a place where I can show my film to people. That cultural exchange is very important.
