Really? No one's got any info on it? It was a neat little prop.
To fill in for those that haven't seen it, Danny Glover, Steve Zahn, and Leelee Sobieski are all on a train and find a wooden box that mysterious man has in his possesion once he dies. Once they each look inside and see what's in it they start to become obsessed with it and try and plot to take it for themselves. It pretty much starts to make them crazy in a way, lol.
The box itself looks about 6 inches wide, 10 inches long, maybe four high. Its got a button that opens some shutters that are behind a carved wooden window. And in the bottom is a slot for the key to open it.
Oh, and in the movie it's pretty much indestructible unless its opened with the key.
