Mumbai: Actor Vicky Kaushal, who is waiting for the release of his upcoming film "Raman Raghav 2.0", says his hectic work schedule has affected his sleep. "The film was shot in 21 days. The schedule was tight and we would finish a massive chunk everyday. The hectic schedule and the intense space of the character started affecting my sleep, and in a few days into the shoot I was functioning on very less sleep," Vicky said in a statement. However, Vicky, who will be seen playing the role of a policeman in the film, said the tiredness helped him with the character. "However, it kind of worked in my favour as it started showing on my face, which worked perfectly for the character," Vicky added. Directed by Anurag Kashyap, "Raman Raghav 2.0" also features Nawazuddin Siddiqui. The film is slated for a June 24 release.
