Movie star Dance stifles scream (7,8)

I believe the answer is:

charles laughton

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

'movie star' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.

'dance stifles scream' is the wordplay.
'dance' becomes 'charleston' (charleston is a kind of dance).
'stifles' indicates putting letters inside.
'scream' becomes 'laugh' (I've seen this before).
'charleston' placed around 'laugh' is 'CHARLES LAUGHTON'.

Can you help me to learn more?

I've seen this clue in The Guardian.
