"Ranbir is a fantastic actor. He can do any film, he is that good," the 50-year-old, who is himself known for his ability to slip into myriad roles, said here in an interview.
Both Aamir and Ranbir were seen together in "PK". While Aamir had a full-fledged role, Ranbir was seen in a cameo at the end of the entertainer.
As of now, Aamir is busy with his film "Dangal", a biopic on the life of wrestler Mahavir Phogat.
