I believe the answer is:

three-ring circus

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

'a frenetic spectacle?' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.

'is her current cgi production' is the wordplay.
'production' is an anagram indicator.
'is'+'her'+'current'+'cgi'='ishercurrentcgi'
'ishercurrentcgi' with letters rearranged gives 'THREE-RING CIRCUS'.

Can you help me to learn more?
