 Between an undated "Amblin" revision and a rewrite by Tom Stoppard (under the pen name Barry Watson) dated May 8, 1988, further changes were made. Stoppard polished most of the dialogue, and created the "Panama Hat" character to link the prologue's segments featuring the young and adult Indianas. The Venetian family is cut. Kemal is renamed Kazim and now wants to protect the grail rather than find it. Chandler is renamed Donovan. The scene of Brody being captured is added. Vogel now dies in the tank, while Donovan shoots Henry and then drinks from the false grail, and Elsa falls into the chasm. The Grail trials are expanded to include the stone-stepping and leap of faith.
