The Indian in the Cupboard was written in 1980 by Lynne Reid Banks, it is the first in a series of books about a boy whose toy Iroquois Indian comes to life. It was made into a movie in 1995.
Omri, a young boy, discovers that when an old cabinet is unlocked with an antique key it has the power to bring small plastic figurines to life. The first toy he puts into the cabinet is a 10cm tall Iroquois Indian figure. Omri is shocked when the toy comes out of the cabinet and tells him that his name is Little Bear, and that he is from the 18th century. But Omri’s troubles really start after he puts a plastic cowboy into the cupboard and then has to deal with “Boone” the cowboy trying to kill Little Bear. Boone wounds Little Bear and Omri must try to bring a plastic WWII medic to life to save him. You will have to read the book to find out what happens next but I can tell you that the book finishes with Omri giving his mother the key so that he won’t be tempted to bring more toys to life. (I guess this idea didn't work so well as The Indian in the Cupboard is the first in a series of five books....)
We have a copy of The Indian in the Cupboard in the Fiction section. The other books in the series, and the The Indian in the Cupboard DVD, are available for borrowing from Upper Hutt Library.
