EXT. DAY. SIGN, WHICH READS, "CAR BOOT SALE THIS WAY ->".
PULL BACK TO REVEAL STREAMS OF PEOPLE HURRYING IN DIRECTION
OF SIGN. NOW IT HAS DEVELOPED INTO A LARGER NUMBER OF
PEOPLE. SOME OF THE PEOPLE ARE PUSHING AND SHOVING TO GET
AHEAD OF THE OTHERS. AS GAPS IN THE CROWD DEVELOP WE SEE A
CONTINUOUS LINE OF SEVERAL VERY HAPPY PEOPLE, PUSHING
FLATBED TROLLEYS AWAY FROM THE SIGN. ON EACH OF THE TROLLEYS
IS THE REAR END OF A CAR. THE COMPLETE CAR-BOOT CAN BE SEEN
INCLUDING THE CAR-BOOT LID.
The Local Carboot Sale (10 second quickie).
I think this has been done before and is a tad obvious. You could have dialogue and have people saying they were going to the car boot sale and use the reveal as a car boot with a sail coming out of it. *groans*
If you 'Groaned' then this visual quickie achieved it's objective. Hopefully not a groan of boredom, but rather a groan of: 'Oh no, another literal play on words'
