Hugh Jackman shares a world record with Patrick Stewart for longest career as a live action Marvel superhero
From the article linked:
Jackman holds the record with fellow X-Men star and Star Trek legend Sir Patrick Stewart (UK); both have had careers spanning 16 years 228 days as Wolverine and Professor Charles Xavier (Professor X) respectively.
Both actors made their first appearance as Marvel superheroes in X-Men (2000), with their most recent appearance was in Logan (2017).
However, Hugh Jackman makes an appearance in Deadpool 2's post-credit scene. Although the role is not credited, other than the actor being thanked by the producers, Deadpool does interact with Hugh Jackman in costume.
Question: Would that appearance not extend Jackman's record one year further than Patrick Stewart?
