An empty Gallery at night. There are a few lights on for security purposes but it is still fairly gloomy, there are paintings hanging on the walls but the main feature of the exhibit is a magnificent statue which takes pride of place in the centre of the room.
The security guard whistles his way by and out of the room.
Tucked just out of sight behind a small white-marble pedestal in the corner of the room lies a small matchbox. A tiny man in tiny overalls pushes the box open and looks forlornly at the huge statue in the middle of the room. After a while he gets out of the match box. With a sigh he bends down and picks up a satchel made out of a dropped handkerchief, slings it round his neck, puts on his little hat and starts pacing his usual route around the room.
He starts picking up the various assorted bits of knick-knacks and bric-a-brac dropped by the Gallery patrons during the day. As he approaches the bin on the other side of the room he glances up at the statue. He sighs and keeps walking but he stops when his foot bumps against a large decorative hairpin that lies on the floor in front of him. He picks up the hairpin and finds that it is broken leaving one end sharp to a point. He starts using it to pick up bits of paper by stabbing them then dropping them into his satchel.
He stops and stares at the point for a few seconds and glances up at the statue again. He looks back over his shoulder to his matchbox house. A huge smile appears on his face. He sprints off down the room and dives into his match box appearing seconds later with a matchstick in one hand and the hairpin in his other. Turning to the marble pedestal he proceeds to hit the head of the match against the back end of the hairpin (effectively using it as a hammer and chisel).
When the sun comes up in the morning a security guard enters the room to find a small copy of the main statue in the corner of the room where the pedestal had been.
This is just the idea. Loglines, Premise, Treatment etc. to follow.
