Imran Khan and Sonakshi Sinha say they both had a fun time dubbing for the Hindi version of animated film Rio 2. Imran had a lot of fun playing Blu as he got to play around with it a lot. He surely had so much fun with this. When a person is doing an animated character, they get to have a little more fun. Since it's a cartoon character he can do things which as a live action actor he can't do, funny sound effects, funny voice, he gets to play around with it.
