"I have been a fan of Neeraj's films, especially 'A Wednesday!'. In this corrupt film world, he is one filmmaker who is stuck to honesty and integrity. He makes films in his genre. He doesn't get into commercial zone just for the heck of it. He is an honest filmmaker," Rana told IANS.
"We tend to corrupt things for different reasons. It's not necessary to have an item song at times... but a few things we do for the sake of commercialism. But there are a few who make true genre films and Neeraj is one of them," he added.
"Baby" also features Akshay Kumar and Taapsee Pannu.
Talking about the film, Rana said: "It's an action thriller. Neeraj was looking for an actor hero who could do all the stunts. That's when he approached me."
The movie will release Jan 23.
