I couldn't resist picking up this licensed replica of the toy shown in the film. Belonging to Gerry Lane's daughter, the 'Subway Sam' toy was highlighted during a pivotal scene, where the mouse's counting game corresponded with the observed time it took for an infected person to turn. The replica toy speaks exactly the way screen-used toy did.
Photo #1 is of the piece in my collection, photos #2 - 4 show the stuffed animal as seen in the film. The video clip at the bottom is not mine (found on YouTube). "Train's in the station!"
