Jon Hamm Reveals the Text His Sister Sent Him After Seeing the ‘Wreckage’ in Landman’s Season 1 Finale

Jon Hamm isn’t sure if he’s ever died onscreen, but his sister definitely doesn’t think he has.

Following the emotional season 1 finale of Landman, which aired Sunday, Jan. 12 on Paramount+ and saw Hamm’s character, M-Tex Oil CEO Monty Miller, succumb to his heart health issues, the 53-year-old actor reflected on his role in the Taylor Sheridan series — and revealed his family’s reaction to Monty’s fate.

Admitting he “can’t remember” if a character he’s played has died onscreen before, Hamm told The Hollywood Reporter, “My sister texted me and she said, ‘I can’t believe I had to watch you die on screen.’ And I was like, ‘Haven’t you seen that before?’ And she was like, ‘No!’”

(Hamm has, in fact, died onscreen before — his character was killed by Dakota Johnson in 2018’s Bad Times at the El Royale.)

The Morning Show actor said that filming his final moments as Monty was “particularly difficult because you’re on your way out, basically, and that’s not fun,” but the “caliber of actors” he was working with — namely Demi Moore, who played his wife Cami Miller, and Billy Bob Thornton, who played his righthand man, Tommy Norris — made it “truly outstanding.”

“You go, ‘This is a spectacular group of people,’ and I just can’t imagine it being any more exciting or fun.”

Hamm admittedly doesn’t have the clearest memory of what his last day on set actually looked like, since it was close to a year ago now, but said that his time on Landman in general was “so condensed.”

“I remember not even meeting Billy Bob until three or four weeks into my shooting schedule. Our time together was brief, but it was certainly fun.”

Hamm’s “other commitments” meant he doesn’t have the ability to “be a series regular on another show,” which adds further context to his character’s death in the season 1 finale. But he told the outlet he couldn’t pass up “the ability to work with Taylor [Sheridan] and Billy Bob [Thornton].”

“Those are guys whose careers I’ve been really paying attention to. They’re just working at the top of their game.”

Looking ahead to season 2, though, he knows there’s “going to be a lot of wreckage to clean up,” particularly for Cami (Moore).

“I think she’s probably pretty pissed that her husband is gone and that her family is devastated. Speaking from experience, those are difficult things to come back from. It’s not a fun thing to lose a parent or to lose somebody close to you.”

In March, Hamm told PEOPLE about his role in Landman as he teased a “lot of back and forth [and] a lot of intrigue” in the series.

“It’s Taylor Sheridan and obviously it’s very well written. It’s very well-researched. It’s a story very well told, and I think it’s an interesting take on what happens when it comes to how we get the stuff that makes our cars and our lives and our planes and everything in our modern world go.”

He also gushed about his costars then, too. “It’s got Billy Bob Thornton and Demi Moore, so it’s a tremendous cast and it’s been super fun to work on. And obviously, Taylor Sheridan’s in charge of everything, so it’s a great project.”
