While both X-Men: Apocalypse and X-Men: Dark Phoenix were massive disappointments, two X-Men shows proved that the franchise can be used properly. The Gifted was a great show that was cut early, while Legion will supposedly end the way showrunner Noah Hawley planned, which is great to hear. Though both shows are heavily X-Men-influenced, neither of them were set in the same universe as the movies.
However, showrunner Noah Hawley did consider making a connection to the older movies as he mentioned wanting to get Patrick Stewart to reprise his role as Charles Xavier for Legion season 3. That would have been one hell of a way to gain interest for the show since we haven't seen Stewart as Xavier since Logan.
Speaking with The Wrap, here is why Hawley eventually decided against casting Stewart:
Though it would have been nice seeing Stewart in the Professor X chair again, Harry Lloyd ended up being a great choice to play as young Charles Xavier. With this being the final season, his eventual confrontation with David should be an epic one.
Legion season 3 currently airs on FX.
