Clue: Good getting on high-priority film (4,4)
Answer: GOLD RUSH
Explanation: Good getting on high-priority film (4,4)
**G** (good) + **OLD** ("getting on") + **RUSH** ("high-priority" as in "rush job") 
*I assume that Redshank is referring to the classic Chaplin movie where the tramp is so hungry he is forced to eat his own boot, but that was called "THE Gold Rush"". There have been movies called "Gold Rush" but none worthy of inclusion in a crossword.
