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

'the dramatic part' is the definition.
(I've seen this in another clue)

I cannot understand how the rest of the clue works.

(Other definitions for role that I've seen before include "Duty" , "Part, portrayal" , "Stage part" , "Part played (in life?)" , "Actor's part" .)

I've seen this clue in the Evening Standard.
