Star once suggested my Herald answer extremely crude (4,6)

I believe the answer is:

hedy lamarr

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

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

'my herald answer extremely crude' is the wordplay.
'extremely' means to remove the middle letters (only the extremes of the word are used).
'crude' is an anagram indicator.
'answer' with its middle removed is 'ar'.
'my'+'herald'+'ar'='myheraldar'
'myheraldar' anagrammed gives 'HEDY LAMARR'.

Can you help me to learn more?

I've seen this clue in the Sydney Morning Herald.
