Corrected entry: It's not clear how Thelma and Louse meet J.D again to eventually give him a ride. Since afterwards they carry on in the same direction it seems that they met him on their way, but then he must have picked another ride and overtaken them, for which there is no evidence. On the other hand, before and after they picked him up there are two shots where they pass the same stretch of road with narrow telegraph poles and a red sign on the right in opposite directions, which means they did go back, but we never see them turning around. (00:44:55 - 00:47:40)
Corrected entry: The gas tanker explodes into a ball of flame after being struck with a .38 Spl caliber bullet. A bullet of this caliber especially fired from a snub-nosed revolver would most likely not even have penetrated the tank. If by some chance it did, it would result in only a small leak which even if ignited would take considerable time to cause the tank to explode.
Corrected entry: There is a time problem in the first part of the movie. Thelma and Louise get to the Silver Bullet bar just as it is getting dark, which at the latest could have been at 9 p.m., if the movie was set in summertime. The events happening inside the bar are all shown in real time, and no more than 10-20 minutes later Harland gets shot and the women speed away. Then they stop by the side of the road, change drivers, and stop at a diner where Louise calls Darryl - which we later learn was at 4 a.m. That's a 7-hour stretch to do only those things.
