Why, when the final scene on a movie has ben filmed, does the director shout '...and that's a wrap' ? Obviously it means that the filming is over but what is the significance of Wrap?
Sorry ladies but films are shot on celluloid reels and when filming was over the director gave the instruction: "Wind, Reel And Print."
Its an acronym.
Are you sure that's not one of those myths? Like 'orl korrekt' for OK - or "For Unlawful Carnal Knowledge"? Or even POSH. Sounds like those words were applied after the event to me...
It almost certainly isn't an acronym, but it may be a backronym, where the letters of an existing word are made into an acronym. Things like golf being an acronym for 'gentlemen only, ladies forbidden' when it is in fact derived frrom the Dutch for 'club'. 'It's a wrap' just means that filming is wrapped up.
I don't think anyone's disputing what wrap MEANS (and they still have wrap parties - as an actor I've been to several!) - but there is no way that it just happened to be a convenient acronym for those words. Don't believe everything you read on the net - Tim's right, Gary's been sadly duped imho.
W.R.A.P means Wind Reel and Print, meaning that the filming is finished. This is from when they used celuloid film reels. The significance just means that the film is complete, nothing too complicated.
