Film star, miscast, dived in van (5,5)

I believe the answer is:

david niven

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

'film star' is the definition.
I don't know anything about this answer so I cannot judge whether this works.

'miscast dived in van' is the wordplay.
'miscast' indicates anagramming the letters.
'dived'+'in'+'van'='divedinvan'
'divedinvan' is an anagram of 'DAVID NIVEN'.

Can you help me to learn more?
