Factual error: During the chase in Paris, the bad guy's car is nicked by the metro train. Instead of lunging forward (in the train's direction - and left in the car's direction) the car jumps 20 meters into the air. Even though the train has a tilting front end, the impact would never create a force in that direction. (01:00:30)

G.I. Joe: The Rise of Cobra (2009)
Ending / spoiler
Directed by: Stephen Sommers
Starring: Dennis Quaid, Channing Tatum, Marlon Wayans, Adewale Akinnuoye-Agbaje, Ray Park
Ripcord (Marlon Wayans) destroys the missile before it hits Washington D.C. and gets arrested after parachuting down. Snake Eyes (Ray Park) kills Storm Shadow. Rex (Joseph Gordon Levitt) dons a new mask, calls himself Commander, and injects McCullen (Christopher Eccleston) with nanomites to control him. The nanomites also heal McCullen and his face becomes metallic; Rex calls him Destro. Duke (Channing Tatum) and bunch of Joe submarines surround the submarine with Rex and McCullen and later they are both imprisoned. Ripcord and Duke join G.I. Joe. Ana/Baroness goes to prison and Duke promises that he'll find a way to get rid of the nanotechnology that's inside her (injected into her by her brother Rex). The President of the United States (Jonathan Pryce) was replaced by Zartan (Arnold Vosloo)(who was injected with nanotech earlier in the movie) when the President entered the bunker. The last scene is Zartan as the President sitting in the Oval Office and whistling "For He's a Jolly Good Fellow"...

Trivia: In the scene where Ripcord and Duke are in the transport and Ripcord pats Heavy Duty on the back and gets his arm twisted as a result, Ripcord makes a crack about Heavy Duty having a "Kung Fu Grip". This refers to some of the earliest G.I. Joe's action figures who were advertised to have the Kung Fu Grip.
Question: In the flashback scene of Rex entering the secret facility, what was he looking at on all of the computer screens and why would he use them later on after he faked his death?





Answer: He was seeing some of the first footage of experiments with the Nanobots by Dr. Mindbender. And the whole plot of the movie is about him using them weaponized and for replacing the president.
