"'It's Entertainment' is a fun film and I enjoyed doing it," Sonu told reporters here Monday at the trailer launch of the film.
"I have not delved into this genre much, so as an actor, it was challenging for me. But when you have a producer like Ramesh (Taurani) and director like Sajid-Farhad, everything becomes easy," he added.
The 41-year-old, who has been part of action thrillers like "Dabangg", "Shootout at Wadala" and "R...Rajkummar", also said: "I enjoyed a lot doing this film. I think the USP of doing comedy films is that you enjoy a lot."
Jointly produced by Ramesh Taurani and Jayantilal Gada, "It's Entertainment" has been directed by writer duo Sajid-Farhad.
Besides Sonu Sood, it also features Akshay Kumar, Krushna Abhishek, Johnny Lever, Tamannaah Bhatia, Mithun Chakraborty and Prakash Raj.
"It's Entertainment", releasing Aug 8, is about a dog called Entertainment.
