“Deadpool & Wolverine” credits four people with creating Wolverine: Len Wein, John Romita Sr., Herb Trimpe, and Roy Thomas.
Wein also gets another acknowledgment in the credits, with a line that reads: “The producers would like to recognize Len Wein for his significant contribution to the X-Men.”
This might be in response to a controversy that emerged in April, in which Christine Valada, Wein’s widow, criticized former Marvel editor in chief Roy Thomas for being credited as a Wolverine co-creator. Typically, comic book writers and artists are given creator credit, not an editor.
Wein, who died in 2017, was best known for co-creating Wolverine and the DC Comics character Swamp Thing. He also co-created the X-Men characters Nightcrawler, Storm, and Colossus.
