The high-octane film opens with what seems to be a normal episode of the Sunday-night TV show.
However, the valuation of a vase at £2 million leads to the owner's son feinting, triggering an action-packed sequence of events.
The vase shoots across the room, and visitors to the show destroy other antiques as they try to catch it, before the vase flies out of the window.
A car then crashes through a wall and smashes into tables of other antique items before bursting into flames.
The BBC news presenter Fiona Bruce jumps clear as the car explodes, coolly catching the vase in a daring leap.
The film ends with the strapline: "TV goes cinematic."
It has been produced in 40-second and 65-second versions for TV, while a 95-second version will show on the BBC HD channel and in UK cinemas.
