It is perhaps more difficult for a radio play to open with an object (which must generally be described) than it is for a screenplay, in which the object may be displayed. However, an eloquent description of the object can capture the audience's attention, as with the opening of the radio drama Grand Central Station, broadcast over the NBC network in the 1930s:
As a bullet train seeks its target, shining rails in every part of our great country are aimed at Grand Central Station, heart of the nation's greatest city. Drawn by the magnetic force of the fantastic metropolis, day and night great trains rush toward the Hudson River, sweep down its eastern bank for 140 miles, flash briefly by the long row of tenement houses south of 125th Street, dive with a roar into the 2 1/2 mile tunnel beneath the glitter and swank of Park Avenue and then ... Grand Central Station! Crossroads of a million lives! Gigantic stage on which are played a thousand dramas daily.
There are several objects here: the rails, the trains, the river, the houses, and the tunnel, all building up to the primary object of Grand Central Station itself.
Objects may not be entirely material. Books and letters are an obvious example, and these often feature in the openings of screenplays or radio plays. One example is that of Spike Jonze's film Her, which opens with a love letter. This is a familiar object, generally regarded as expressing much more than its material components of ink and paper. However, in this case, the letter has been manufactured to order, rather than being a genuine expression of feeling. As is often the case when the screenplay opens with an object, the fake emotion of the letter encapsulates one of the film's major themes.
