Set in Goa, Homi Adajania's directorial venture also stars Deepika Padukone.
"I am a new actor, so for me, working with these actors is like a dream come true. I always used to tell Homi that this film is like an acting class for me," the actor told reporters Thursday on the sets of Disney's chat show "Captain Tiao" here.
"I observed and noticed how veteran actors behave towards their work. Perhaps their experience will reflect in my work as well. It was great working with them all," he added.
Shot in English, "Finding Fanny" was such an opportunity for Arjun that he wanted to grab it with both hands, though he was initially skeptical.
"Initially, I thought it would be difficult. But I feel an actor should grab the opportunity of doing different things. So, I took a chance.
"As far as the reaction to the trailer is concerned, people think that I can speak English also fluently. However, I am still learning to act properly in Hindi. It was a new chance for me and I didn't want to lose it," said Arjun.
The satirical comedy is set to release in September.
