Ryan Reynolds has spent the last few years playing various flavors of the Deadpool character across a number of movies. His latest film, Free Guy, also has him play more or less the same character archetype, but with less homicidal mania.
During promotional appearances for that film, Reynolds has been asked about Deadpool 3. He has obligingly shared his predictions too, and apparently he doesn't have much more info than the rest of us.
Reynolds had a pretty bumpy ride leading up to the success of the first two Deadpool movies. Appearing as an... unusual take on the character in X-Men Origins: Wolverine, a movie that was widely panned by critics, and later appearing in the similarly derided Green Lantern as the titular hero, not only torpedoed is future in superhero projects, but threatened to sink his career entirely.
When test footage for a more traditional take on Deadpool was leaked to an astonishingly positive response, the redemption arc of this story finally begun. The two Deadpool movies were commercial and critical successes, effectively erasing the troubles caused by Wolverine and Green Lantern.
