I believe the answer is:

charliechaplin

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

'this star's?' is the definition.
The definition suggests a singular noun which matches the answer.

'celia and ralph played in prominent feature' is the wordplay.
'and' means one lot of letters go next to another.
'played' is an anagram indicator.
'in' indicates putting letters inside.
'prominent feature' becomes 'chin' (I've seen this before).
'celia' after 'ralph' is 'ralphcelia'.
'ralphcelia' anagrammed gives 'arliechapl'.
'arliechapl' placed inside 'chin' is 'CHARLIE CHAPLIN'.
