In the DC Extended Universe feature films, she was portrayed by Kiersey Clemons in Zack Snyder's Justice League (2021) and The Flash (2023).

Iris West works as a reporter for Picture News, based in Central City, and is the fiancée of Barry Allen, who is secretly the Flash.

After years as a prominent presence in the Flash's life and in Central City, She was killed by Professor Zoom during a costume party.

Don marries the descendant of Professor Zoom, Meloni Thawne, hoping to end the feud between the two families.

[12] Iris takes Bart to the past to enlist the aid of her nephew (by then, Wally had taken the mantle of the Flash) in saving her grandson.

This time she is kidnapped by Polaris and Abra Kadabra and forced to write everything she knew about the future so that they could have a "roadmap into tomorrow" for their plan of world conquest.

[14] After this incident, Iris went someplace where no one would find her so that she could concentrate on writing the book The Life Story of the Flash, which was published by Keystone Press in 1997.

[16] A mysterious hooded figure enlists the help of Zoom[17] to attack Bart while he confronts Captain Cold, and later reveals herself as Iris.

[19] Iris spends some time as part of a Darkseid-resistance cell operating out of the Hall of Justice alongside Black Lightning, Green Arrow, the Ray, Linda Park and her two children.

[22] She is also shown to be much younger than she previously had appeared (she was depicted as a middle-age woman after the events of Crisis), about the same age as when Barry first met her.

It is later implied by the resurrected Professor Zoom that Iris's rejuvenation is a side effect of close contact to her husband's Speed Force since Final Crisis.

Since the Flash Family defeated Grodd and stop the Negative Speed Force from spreading Central City, both she and Barry have rekindled their romances with each other.

A year later in 1958, after Barry had retired from crime fighting and the subsequent appearance of the Centre, Iris had known for some time that her husband was the Flash and did not reveal this until she convinced him to become a hero once again.

[30] In the Flashpoint miniseries (an event prior to the New 52 relaunch, when an alternate timeline was created by the Flash[31]), Iris West is unmarried and in a relationship with someone called "John" at the Central City Citizen, where she works.

[32] Later Iris is seen with her nephew and cameraman, Wally West, covering a battle between Citizen Cold and Mister Freeze.

Citizen Cold attacks Pied Piper, but Iris uses one of his own weapons to freeze him in a block of ice, just as he had Wally.

Later, Flash sees Iris being arrested by Girder and King Shark for treason against the Regime from joining a Central City Insurgent group.

Barry talks with her, and she tells him that her faith in him was shattered five years ago when she was undercover in Australia where she witnessed Superman and Wonder Woman brutally beat and cripple a rebellious hero named Galaxor while Flash did nothing to help the young man (who committed suicide shortly afterwards though that later turns out to be a myth).
