Actor-filmmaker Sohum Shah of "Tumbbad" fame is happy to be a part of the "extremely engaging" film "The Big Bull", which also stars Abhishek Bachchan. "I am thrilled to be a part of this film. The story of the film is extremely engaging. When I started reading the script, I simply couldn't keep it aside till I reached the end, it was so engrossing. Plus the character I play is very interesting. Everything about it was so good that I was compelled to say a 'yes' immediately," said Sohum about the film produced by Ajay Devgn. Helmed by Kookie Gulati, "The Big Bull" is a crime drama. Sohum had to undergo intense preparations for his character. Sohum said: "There is a lot of research gone into my character. My character's body language, thinking abilities, the look, everything is very different from what I have done before. It's too soon for me to reveal anything else about my character, but I would like to say that the process was fun and I learned a lot as an actor while preparing for this role."
