Director of a circus that's starring ... me, surprisingly (10)
I believe the answer is:
ringmaster
'director of a circus' is the definition.
'ringmaster' can be an answer for 'director' (thesaurus). I'm not sure about the 'of a circus' bit.
'starring me surprisingly' is the wordplay.
'surprisingly' indicates anagramming the letters.
'starring'+'me'='starringme'
'starringme' with letters rearranged gives 'RINGMASTER'.
'that's' acts as a link.
Can you help me to learn more?
(Other definitions for ringmaster that I've seen before include "Circus controller" , "Circus MC" , "circus performer" , "Top top man" , "Circus employee" .)
