Ryan Reynolds Enlists Grant Gustin With Numerous The Flash Nods In New Ad: "You'll Always Be My Barry"

Ryan Reynolds and Grant Gustin have joined forces in a recent advertisement filled with numerous nods to The Flash. Gustin, who portrayed Barry Allen for nine seasons in the Arrowverse's DC Universe TV series, bid farewell to his rendition of the hero earlier this year in The Flash Season 9's conclusion.

While Reynolds has also donned the mantle of a DC superhero, his portrayal of Green Lantern is not as renowned as his upcoming venture in Deadpool 3, where he will introduce Wade Wilson into the Marvel Cinematic Universe.

MNTN, the advertising company, took to Twitter to release a new video that humorously brings together Ryan Reynolds from Deadpool and Grant Gustin from The Flash.

In the advertisement, Gustin takes on the role of the fictional character Seymour Roas, and it includes numerous allusions to The Flash.

 As the Arrowverse came to a close, and Gustin's portrayal of Barry didn't transition into the new DC Universe canon, it appears that the actor's tenure as The Flash has come to a definitive end.

 In the ad, Reynolds remarks to Gustin, "You'll always be my Barry," to which Gustin playfully retorts, "You'll always be my Hal," teasing Reynolds' portrayal of Hal Jordan in Green Lantern.

The collaboration between Reynolds and Gustin in this new ad has certainly sparked excitement among fans and has ignited speculation about the potential for a Marvel and DC movie crossover. 

Despite the MCU and the Arrowverse/DCEU running concurrently for many years, the prospect of a crossover has never seemed more feasible, and a significant reason for this is the presence of James Gunn at the helm of the rebooted DC Universe.

James Gunn gained immense popularity for his exceptional work on the Guardians of the Galaxy franchise at Marvel Studios. He now holds a key creative role in the revitalized DCU. 

Given his previous experience with the MCU and his close relationship with Marvel Studios president Kevin Feige, Gunn could play a pivotal role in making a Marvel and DC crossover a reality. 

Notably, Gunn confirmed that discussions about a Marvel and DC crossover have taken place, albeit in a lighthearted manner, and any such crossover is still several years away.

The DCU is set to truly kick off with the release of "Superman: Legacy" in 2025, giving it time to establish itself as a significant cinematic universe. 

This gradual buildup could potentially pave the way for the long-anticipated crossover with the MCU.

As the concept of the multiverse becomes more prevalent in superhero movies and shows over time, the stage could be set for a crossover when the DCU is ready.

This could also involve the return of characters like The Flash's Gustin and other Arrowverse characters, who are well-versed in the multiverse, as well as the inclusion of characters from previous Marvel and DC franchises, making it the most monumental crossover event in history.
