One rushing to get hold of Charlie’s weepie film (4-6)
I believe the answer is:
tear-jerker
'weepie film' is the definition.
'one rushing to get hold of charlie's' is the wordplay.
'one rushing' becomes 'tearer' (someone who rushes or tears about).
'to get hold of' indicates putting letters inside.
'charlie' becomes 'jerk' (both can mean a stupid person).
'tearer' going around 'jerk' is 'TEAR-JERKER'.
(Other definitions for tear-jerker that I've seen before include "Highly sentimental story, film etc" , "Weepie" , "Extravagantly sentimental book, play, etc" , "tale that's emotional" , "Tragedy perhaps" .)
