'star' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.

'greece with character there above dress circle' is the wordplay.
'greece' becomes 'Gr' (abbreviation).
'with' means one lot of letters go next to another.
'character' becomes 'eta' (letter of the Greek alphabet).
'there above dress circle' becomes 'garbo' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'gr'+'eta'+'garbo'='GRETA GARBO'

'from' is the link.
