If Google is anything to go by.
Google has given fans of X-Men and Marvel in general a tasty but possibly misleading bit of news today. Somebody, for some reason, was searching "famous Hugh Jackman movies" on Google and they got a surprising result: Avengers: Endgame. This is no lie, I tried it myself. It not only comes up, but is the very first movie on the search, ahead of all his other appearances in X-Men and his role as Jean Valjean, who stole just one piece of bread, in the very long musical Les Misérables:
A cameo for Jackman has not been announced by Marvel and, as Complex points out, Fox and Disney haven't settled their deal on the rights to the X-Men franchise, but maybe Fox is allowing a cameo as a show of good faith. On the other hand, Jackman has said publicly that he's done with the role. In an interview with Screen Rant, he is asked "is this your last time as Logan?" and he replies with a simple "yeah." But, the fact remains that Avengers: Endgame comes up when you search for Hugh Jackman on Google and it's not clear how this would be a mix-up. Let's hope that it's not.
