In Season 3 of Tulsa King, Beau Knapp joins the cast as Cole Dunmire. This new character is introduced as the son of Jeremiah Dunmire, a powerful figure in the liquor business, and his arrival shifts the balance of several scenes in the season opener.

Tulsa King moved into a phase where family influence and outside threats intersect, and Cole’s behavior in the first episodes adds tension between the Dunmire family and Dwight Manfredi’s crew. Knapp’s casting signals a deliberate choice to add a younger, volatile presence to the series.

His Cole Dunmire is written as a trust-fund country boy with a reckless streak, and early episodes use that contrast to drive conflict at a family dinner and during a late-night confrontation in Episode 2. Tulsa King Season 3 premiered on September 21, 2025, and the new episodes set up this family-versus-empire storyline.

Beau Knapp was born in Los Angeles in 1989 and began acting in the late 2000s. He started with small film parts and gradually moved into larger supporting roles.

Early on, he appeared in Super 8, which gave him exposure in a major studio feature, and he continued to take roles that fit both genre films and character dramas. Over the years, his name began to appear in crime thrillers and action pictures, which shaped the kinds of parts he was offered.

Knapp’s film work includes The Signal, Run All Night, Southpaw, and The Nice Guys. He also played a central antagonist in Death Wish and took parts in ensemble pieces such as Billy Lynn’s Long Halftime Walk.

Those roles often placed him opposite lead actors with established screen personas, which gave him chances to play challenging supporting turns rather than lead parts at first. This pattern of gritty or unpredictable characters makes the transition to Cole Dunmire feel consistent with his past choices.

On television, Beau Knapp has appeared in series like Seven Seconds and The Lost Symbol, and he played Drew Franklin in SEAL Team. Those TV roles allowed him to explore longer character arcs and to work in ensemble environments, which is similar to the demands on him in Tulsa King. Television credits also helped him build a résumé that casting directors can point to when adding him to a larger franchise or prestige series.

Cole Dunmire functions as a narrative catalyst in Tulsa King Season 3. His actions create immediate problems that force older characters into quick decisions, and that allows the writers to show how family loyalty and business interests collide.

For Beau Knapp, the role is a step into more visible ensemble drama; he shares scenes with established names, and those scenes let him play a character who is both privileged and unstable. The part does not change his past credits, but it places him in a high-profile series that could lead to more regular television work.


Overall, the choice to cast Beau Knapp as Cole Dunmire fits the needs of Season 3 of Tulsa King. The Tulsa King writers wanted a younger antagonist whose personal chaos has direct effects on family power and the larger criminal landscape.

Tulsa King viewers who follow Knapp’s career will find this role continuous with his earlier work in films and TV dramas, while also new in the sense that it pairs him with a long-running series cast and a wider, weekly audience.
