Avatar perhaps ranks No 1 in Hollywood I suspect (7)
I believe the answer is:
krishna
'avatar' is the definition.
(Krishna is an example)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for krishna that I've seen before include "Hindu deity - Sikh ran (anag)" , "Hare ..., religious sect based on Vedic scriptures" , "Most celebrated of Hindu deities" , "Hare ..., religious sect whose devotees wear saffron robes" , "divine figure" .)
