 A recreation of the Body Worlds exhibit provided a setting for one scene in the film . Among the Body Worlds plastinates featured in that scene were the Poker Playing Trio ( which plays a key role in one scene ) and Rearing Horse and Rider . The exhibition 's developer and promoter , German anatomist Gunther von Hagens , also has a cameo appearance in the film , although only his trademark hat is actually visible on screen .
