Film Aussie's welcome to screen about animal (9,3)
I believe the answer is:
groundhog day
'film' is the definition.
(I know that Groundhog Day is a film)
'aussie's welcome to screen about animal' is the wordplay.
I cannot really see how this works, but
'about' could be 'round' (I've seen this in other clues) and 'round' is found within the answer.
'animal' could be 'hog' (hog is a kind of animal) and 'hog' is found within the answer.
'aussie's welcome' could be 'gday' (greeting used in Australian English) and 'gday' is found within the answer.
This accounts for all the letters.
This explanation may well be incorrect...
(Other definitions for groundhog day that I've seen before include "Picture" , "Situation in which events are continually repeated" .)
