Cobra Commander appears in the movie ''[[G.I. Joe: The Rise of Cobra]]'' played by [[Joseph Gordon-Levitt]]. Gordon-Levitt wore a mask and prosthetic makeup underneath. Upon seeing concept art of the role he was being offered, Gordon-Levitt signed on because; "I saw the designs and drawings of the way they interpreted my character for this movie – the costume, the whole getup – and I was like, 'Oh, wow. I get to be that guy? Fantastic. Sign me up. Please. Thank you.'"<ref>{{cite web |url=http://www.military.com/entertainment/movies/movie-news/gordon-levitt-plays-cobra-in-g.i.-joe-film |title=Gordon-Levitt Plays Cobra in 'G.I. Joe' Film |date=2009-04-17 |access-date=2009-10-03|author=Derrik J. Lang |publisher=Military.com}}</ref> Gordon-Levitt described his vocal performance as being half reminiscent of Chris Latta's voice for the 1980s cartoon, but also half his own ideas, because he felt rendering it fully would sound ridiculous. The hood was not used in the movie, due to concerns that it would resemble the hood used by the [[Ku Klux Klan|KKK]].<ref>{{cite web|url=http://www.shockya.com/news/2009/02/14/toy-spoiler-possibly-reveals-gi-joe%E2%80%99s-cobra-commander/|title=Toy Spoiler Possibly Reveals G.I.

For most of the movie, he is referred to as '''The Doctor''', a "mad" scientist working with [[Destro|James McCullen]] researching military uses of nanomites. It is revealed that he was '''Rexford G. "Rex" Lewis''', the younger brother of [[Baroness (G.I. Joe)|Ana Lewis]], and once a military science officer alongside Duke, his friend and mentor. When an enemy East African location is destroyed prematurely by an air strike, Rex is presumed dead. However, just prior to the explosion, Rex witnessed McCullen's experimental research on nanomites, conducted by [[Doctor Mindbender]]. Surviving the incident, scarred & requiring a special mask to breathe, Rex learns from Mindbender and perfects the nanomites. He uses his own sister as a test subject in creating the [[Viper (G.I. Joe)|Neo-Vipers]], making her the Cobra agent known as the Baroness. Rex holds a grudge against Duke for leaving him to die. When Duke is captured, Rex reveals himself, as he attempts to inject Duke with the nanomites, the Baroness overcomes her programming and saves Duke, while Rex escapes with a badly burned McCullen. Rex uses specially made nanomites to heal McCullen's face, which also encases it in a living, silver-like metal. Dubbing him "Destro", Rex puts on a new breathing mask and tells McCullen to call him '''Commander'''. Although he is arrested and placed in a high security prison aboard the USS Flagg, Cobra Commander's master plan has only begun, with [[Zartan]] disguised as the President of the United States.

Cobra Commander returns in ''[[G.I. Joe: Retaliation]]'', played by [[Australians|Australian]] actor [[Luke Bracey]] and voiced by [[Robert Baker (actor)|Robert Baker]].<ref name="Manning">{{cite web|last=Manning |first=Michelle |url=http://www.popsugar.com/Robert-Baker-Interview-GI-Joe-Lone-Ranger-Video-28427210 |title=Robert Baker Interview on G.I.

Joe: A Real American Hero'' cartoon.

In the movie, Cobra Commander has been transferred from the FLAGG to another high-security prison in Germany alongside Destro, where he is being force-fed a paralyzing drug whilst floating in a water chamber. He is soon broken out by [[Storm Shadow (G.I. Joe)|Storm Shadow]] and [[Firefly (G.I. Joe)|Firefly]], but Destro is left behind and Storm Shadow is injured as the base is destroyed. After sending Storm Shadow off to the Himalayas to heal, Cobra Commander retreats to his own base of operations, where he meets with Zartan (still disguised as the President). They reveal Project Zeus, a super weapon, which uses kinetic bombardment and targets several prominent cities. Cobra Commander demonstrates the magnitude of the weapon's power in front of the world's leaders by destroying London. The Joes are able to stop Cobra Commander before he unleashes the full power of Zeus, but the terrorist leader escapes after the deaths of Zartan and Firefly.

Cobra Commander will be appearing in ''[[G.I. Joe: Ever Vigilant]]'' for a cameo.<ref>{{cite web|url=http://thathashtagshow.com/2018/05/g-i-joe/|title=EXCLUSIVE: Character Details About The G.I.
