Nawazuddin Siddiqui, who is known for his varied roles, puts a lot of hard work and dedication while preparing for a role. So it wasn't a surprise when the actor showed his prowess while shooting for his next, 'Raman Raghav 2.0' .
According to a report in The Indian Express, the actor was supposed to deliver a 10-minute monologue which was shot from 10 different angles during the shoot of the film. As a result, the actor ended up speaking for 300 minutes maintaining the tone and style of his voice.
The entire exercise however took a toll on the actor as he experienced a total blackout at the end of the shoot and couldn't talk for some time.
