The Fort Worth preview screening of May 1995 was an alternate version, featuring:
Slightly different music cues in some scenes and in the pre-title intro;
Different music for the "finding the cave" sequence (the music used in the preview screening was identical to that used in the "crossing the desert" sequence,");
A different sound mix and sound effect tracks;
Minor variations in the dialog track (i.e., when Ian first intercepts David at the college, he shouts "Whoa!" When Travers identifies David in the bar, David answers "That's right" rather than "Yes.");
Different visual effects in the final garden sequence;
