After Stardust, Goldman became a frequent collaborator of Director Matthew Vaughn, co-writing his next films, the comic book adaptations Kick-Ass (2010) and X-Men: First Class (2011). Both films met strong praise amongst film critics. Kick-Ass enjoys a cult following and X-Men: First Class is considered by many critics the best of all X-Men films up to now. Rotten Tomatoes consensus says: "With a strong script, stylish direction, and powerful performances from its well-rounded cast, X-Men: First Class is a welcome return to form for the franchise."
