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

'amazing thailand win against italy' is the wordplay.
'amazing' is an anagram indicator.
'against' says to put letters next to each other.
'italy' becomes 'i'.
'thailand'+'win'='thailandwin'
'thailandwin' with letters rearranged gives 'withnailand'.
'withnailand'+'i'='WITHNAIL AND I'
