K.B. Ganapathy has a nice anecdote in today's Star of Mysore on Dr Raj Kumar. Apparently in the very year Dr Raj won a national award for best actor, Ambarish too won the award for best villain.
"Ambarish had gone to receive the award with his mother. Soon, Dr Raj entered the hall. Ambarish's mother asked him to go and meet Dr Raj, congratulate him and take his blessings.
"Ambarish, however, did not listen to his mother. In a few minutes, though, Dr Raj, on spotting Ambarish, walked upto him and profusely congratulated him, thus embarrassing mother and son."
