The X-Men film franchise definitely feels like it’s in an era of transition right now, with Hugh Jackman set to retire from the series with his final outing as Wolverine in Logan and 20th Century Fox looking to change things up a bit for their next full X-Men release, titled Supernova, after the disappointing reaction to last summer’s X-Men: Apocalypse.

While we already know that Sophie Turner is reprising her role as Jean Grey in Supernova — and although nothing has been confirmed, we’re assuming that the likes of Tye Sheridan (Cyclops), Alexandra Shipp (Storm), and Koki Smit-McPhee (Nightcrawler) will return as well — it’s unclear if the star trio of James McAvoy, Michael Fassbender, and Jennifer Lawrence will return for a fourth outing or not, as their contracts concluded with Apocalypse. That being said, a recent Instagram post from McAvoy suggests that the Scottish actor may be gearing up to return as Professor X:

McAvoy posted two photos to Instagram, joking that he had dinner with the man busy having a “multi-generational three-way relationship with two professors,” with one image showing X-Men writer/producer Simon Kinberg sitting down with Patrick Stewart for a meal, and another of himself with Kinberg. The caption ends with McAvoy stating that he “can’t wait for the summer.”

With Supernova set to begin filming in June, McAvoy’s claim that he can’t wait for the summer would appear to line up with this scheduling, although of course he could be referencing anything. We’ll have to wait for an official casting announcement to be made, but it wouldn’t be surprising to see McAvoy return for another X-Men film, as his portrayal of Charles Xavier has not only been warmly received by fans, but seems to be a role he enjoys playing. And even though McAvoy has regrown his hair after shaving it all for Apocalypse and M. Night Shyamalan’s Split, we’d imagine he would do it all again if Fox made the right offer.
