Many of the timelines on this site contain events that would alter movie history, as we know it...
For example: Keynes' Cruisers has changed the Malaya & Burma Campaigns to the point where "Bridge Over the River Kwai" wouldn't be made. On the other hand, a "Monty of Malaya" might be filmed. Also, there's a third spinoff possibility: "They Were Expendable" probably is made, but an altogether different plot and screenplay from what we know.
