'film festival's baseless' is the definition.
I don't know anything about this answer so I cannot tell whether this works.

'worry about american work' is the wordplay.
I cannot quite understand how this works, but
an anagram of 'worry' is 'ryrow' which is within the answer.
'about' could be 'ca' (abbreviation for 'circa') and 'ca' is located in the answer.
This may be the basis of clue (or it may be nonsense).

Can you help me to learn more?
