Billy Bob Thornton was well aware that playing an oil company’s crisis expert in “Landman” wouldn’t came with any glamor.

At 69 years old, Thornton portrays the crude-talking Big Oil troubleshooter Tommy Norris in the Paramount+ series, crafted by executive producers Taylor Sheridan and Christian Wallace. The show is inspired by Wallace’s 2020 “Boomtown” podcast that detailed the effects of the West Texas oil boom. Becoming Tommy involves more than getting filthy, and it certainly comes across.

“I feel like I look older in ‘Landman’ than I do in reality,” Thornton shares, noting how Norris’ disheveled persona contrasts with his stylish ex-wife Angela (played by Ali Larter). “Tommy rarely fixes his hair, never shaves, and is generally disheveled with dirt on his skin and clothes.”

For Thornton, this role is a strong entry point into the Sheridan universe, which also includes hits like “Yellowstone” and “Tulsa King.” He now enjoys a quieter life in Hollywood with his wife Connie Angland, having been married for a decade, in contrast to his more public relationship with former spouse Angelina Jolie (married from 2000-2003).

The actor, known for roles like in “Bad Santa” and for winning an Oscar for “Sling Blade,” discussed “Landman” with YSL News, highlighting that Episode 3 will be available to stream this Sunday.

Question: You wear Tommy Norris’ jeans quite low, which definitely has a West Texas feel. How do you pull that off?

Thornton: They sit pretty low, especially with a tucked-in shirt. And honestly, I don’t have much of a butt. George Carlin might say, “He’s a guy who needs to wear two wallets to look like he has an ass.” Ali (Larter) would frequently pull my pants up on set! Each day she’d go, “Babe, come here,” and literally tug at my waistband.

Tommy is known for verbally confronting critics regarding his Big Oil job and lifestyle. Are you concerned about stepping into political waters while portraying such a rough character?

If someone criticizes Tommy, he’ll passionately defend his way of making a living. That’s the reason for his outbursts. But if a breakthrough occurs that allows vehicles and planes to run on water, those oil executives would pivot to selling water. Essentially, these business people are out to make money. The series doesn’t take sides; it depicts the oil industry’s nuances. But the issues are often polarized. If I starred in a film about Jack the Ripper, and the actor was exceptional, it wouldn’t imply that audiences approve of Jack the Ripper. The goal is to view this as entertainment.

We can all rally behind Tommy as he insists on getting his change from the bartender in Episode 1 because the tip culture is indeed excessive, right?

Exactly! Plus, as a celebrity, there’s an expectation to tip even more. There are entire sections in magazines judging tipping behavior, labeling someone as “cheap.” This has led me to leave 100% tips before. My wife often says, “We’ll go broke if you keep this up.” But I really don’t want to be featured in some magazine for that.

You reunite with Demi Moore, who plays Cami Miller, the wife of Monty (Jon Hamm), the oil company owner. Was this like a reunion from “Indecent Proposal” back in 1993?

I appeared in “Indecent Proposal” briefly as a character named Day Tripper. I was around for six weeks mostly on standby, and they ended up cutting one of my scenes out. Nonetheless, I got to bond with Demi and Bruce (Moore’s ex-husband) during that time, and Demi frequently brought her kids to the set. Over the years, I’ve acted in three films with Bruce, so we’ve maintained a close connection.

As an Arkansan, you must realize that Tommy’s harsh comment about the University of Alabama’s Crimson Tide will stir some reactions.

It’s just one line I had to deliver, and I thought, “Oh boy.” I’ve always respected (former head coach) Nick Saban, and even though I root for the Arkansas Razorbacks, I keep an eye on Alabama’s games. I have a great affection for the people of Alabama; our band is well-loved there. I certainly hope they don’t take it the wrong way.

It’s important to remember that this is just a television show. Let’s keep things in perspective.

In “Landman,” there is a strong criticism of Pop-Tarts, with comparisons being made between eating these highly processed snacks and smoking. What’s the reasoning behind this?

There are many breakfast options available. But what exactly is a Pop-Tart? It’s mostly just a shell with very little filling inside.

You seem to have a strong dislike for Pop-Tarts.

I’m not against Pop-Tarts. In fact, I enjoy them! But I choose not to consume any processed foods.

In the show, Tommy often opts for Michelob Ultra, which becomes the punchline of many jokes. Do you think this is an unusual case of product placement, or does it fit naturally into the story?

I don’t focus on product placement. It’s an interesting inquiry though, as I’ve noticed other shows using products that are often criticized. While filming, I don’t actually drink Michelob Ultra. What I consume is mostly water to stay hydrated.
