Typical Stan Lee role (5)
I believe the answer is:
cameo
'typical stan lee role' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for cameo that I've seen before include "Miniature picture" , "Ornament or miniature performance" , "Small part for star actor" , "Carved brooch - small role" , "Piece of jewellery; small role" .)
