How did Deadpool survive in X-Men Origin Wolverine?

In "X-Men Origins: Wolverine," Deadpool, portrayed by Ryan Reynolds, survives due to his regenerative healing factor, which is a result of the Weapon X program's experiments. However, the film showcases a controversial depiction of the character, where his mouth is sewn shut, limiting his ability to speak. Ultimately, he survives the events of the film, despite the chaos and dismemberment, because of his enhanced abilities, though the film's portrayal diverges significantly from the comic book version of Deadpool.
