I believe the answer is:

marco polo

I'm a little stuck... Click here to teach me more about this clue!

'famous traveller' is the definition.
'marco polo' can be an answer for 'traveller' (13th-century explorer). I'm unsure of the 'famous' bit.

'spoil cool production about po's' is the wordplay.
'spoil' becomes 'mar' (synonyms).
'production' indicates anagramming the letters.
'about' indicates putting letters inside.
'cool' with letters rearranged gives 'colo'.
'colo' going around 'po' is 'copolo'.
'mar'+'copolo'='MARCO POLO'
