We’ve all assumed that when Hugh Jackman was announced for “Deadpool 3,” reprising his Logan/”X-Men” one more time—after avowing for years, he was done with the role previously—that it was all the doing of Ryan Reynolds and the director Shaun Levy. Both had a relationship with Jackman; Levy directed him in “Reel Steel” ages ago, and the two actors obviously have quite the relationship on social media with all the gangs and pranks they play on each other (and, of course, Deadpool/Reynolds and Wolverine/Jackman did already act side by side in “X-Men Origins: Wolverine,” and of course, Reynolds mocked that hard in the meta-end credits of “Deadpool 2”).
