He says he prefers Kangana's Haryanvi avatar in the Aanand L. Rai directorial.
Imran enjoyed "Tanu Weds Manu Returns", which also features R. Madhavan and Deepak Dobriyal, and found Kangana very good in both roles -- as Tanu as well as Datto.
"I really enjoyed the film and Kangana was superb in her double role. But I preferred Datto's character over Tanu's," the actor said in a statement.
In fact, Imran watched the film twice.
Imran liked all aspects of the film; the script, the direction, the supporting cast, but he was biased to Kangana and actively discussed her performance with his team, according to a source.
Produced by Eros International and Colour Yellow Productions, sequel to the 2011 entertainer "Tanu Weds Manu" focuses on the rediscovery of love between a married couple. It has struck gold at the box office raking in over Rs.165 crore worldwide.
Meanwhile, "Katti Batti", directed by Nikhil Advani, is a love story. It will release in September.
