SP Balasubramaniam, the singer who is fondly referred to as ‘SPB’ or ‘Balu’, has been associated with Kamal for long. In fact, in many movies, he served as the voice of Kamal. In a concent arranged by the Bay Area Telugu Association, SPB had some nice words to say:

Balu said that there very few actors who can completely justify all his songs with a right mixture of emotions, feelings, dances, and body language and that Kamal Hassan is one of them.

Bharat Kumar played the funny kid with a hole in his heart (whose father was played by Jayaram) in Panchatantiram, alongside Kamal. In an interview, he had this to say about his experience:

Kamal Haasan is a big artiste. In fact, I am afraid of doing a role along with him. But he is quite free with me. He always keeps calling me a friend. Whenever, I did a scene accurately, he used to kiss me.
