When Ashley (Adria Arjona) drops divorce bombshells on her husband Carey (Kyle Marvin), his search for solace leads him to Julie (Dakota Johnson) and Paul (Michael Angelo Covino) – a couple championing open marriage as their key to happiness. But when Carey oversteps their unconventional boundaries, he triggers a chain reaction of jealousy, betrayal, and shattered trust that engulfs all their relationships.

This sharp-edged exploration of modern love and moral chaos blends dark humor with emotional wreckage. Directed by the team behind The Climb, Splitsville features an electrifying ensemble cast primed to dissect commitment, desire, and the messy consequences of blurred lines. Discover the players in this relational powder keg below.

Splitsville complete cast list

1. Dakota Johnson as Julie

Dakota Johnson (born 1989) skyrocketed as Anastasia Steele in the Fifty Shades trilogy before showcasing indie range in The Peanut Butter Falcon, Suspiria, and Cha Cha Real Smooth. Her production company TeaTime Pictures backs female-driven projects like Am I OK?, cementing her industry influence.

As Julie, Johnson channels her signature blend of vulnerability and quiet intensity. Her character’s open-marriage evangelism masks hidden insecurities – a perfect vehicle for Johnson’s talent in exposing emotional contradictions beneath cool facades.

2. Adria Arjona as Ashley

Puerto Rican star Adria Arjona (born 1992) broke out in Good Omens and Pacific Rim: Uprising, then stole scenes as Bix in Andor. Films like 6 Underground, Morbius, and Hit Man (2024) showcase her action-drama range.

Arjona’s Ashley is the catalyst – a woman reclaiming autonomy. Expect layered defiance from this performance, weaponizing Arjona’s ability to balance strength with wounded resilience in divorce’s emotional trenches.

3. Kyle Marvin as Carey

Kyle Marvin (born 1986) co-wrote/starred in Sundance hit The Climb (2019) and appeared in WeCrashed and Winning Time. His background in improv (UCB Theatre) fuels naturalistic, everyman charm.

As the heartbroken Carey, Marvin’s “nice guy” persona makes his boundary-crossing descent relatable. His chemistry with Johnson/Covino will drive the film’s central moral spiral from sympathy to chaos.

4. Michael Angelo Covino as Paul

Covino (born 1988) co-created and directed The Climb with Marvin, earning Independent Spirit Award nods. His acting credits include The Menu and Station Eleven. Known for dry, intellectual intensity.

Playing open-marriage architect Paul, Covino embodies rationalized chaos. His character’s smug control fractures when Carey disrupts the system – a role demanding comedic arrogance masking volcanic rage.

5. Simon Webster as Russ

Rising actor Webster appeared in Transplant (Dr. Riley) and Star Trek: Discovery. His stage work includes The Sound of Music (West End). Russ likely represents traditional relationship values – a foil to the central chaos. Webster’s grounded presence hints at a voice of reason (or judgment) amid the relational storm.

6. Charlie Gillespie as Jackson

Gillespie (born 1998) gained fame as Luke in Julie and the Phantoms. Other credits: The Rest of Us and I Am Not Okay with This. Projects showcase youthful charisma and musicality. Jackson’s role suggests Gen-Z perspective on the older characters’ drama – possibly a destabilizing force or naïve observer. Gillespie’s casting leans into generational tension.

7. David Castañeda as Fede

Castañeda (born 1990) stars as Diego Hargreeves in Netflix’s The Umbrella Academy. Films include Sicario: Day of the Soldado and The Guilty (2021). Fede likely embodies reckless hedonism. Castañeda’s history with morally grey characters suggests a wildcard who exploits the group’s unraveling for his own gain.

8. O-T Fagbenle as Brent

British star Fagbenle (born 1981) earned Emmy buzz as Luke in The Handmaid’s Tale. Credits span Maxxx, Black Widow, and Les Misérables (BBC). As Brent, Fagbenle adds sophisticated gravity – potentially a therapist or detached observer. His presence raises stakes, forcing characters to confront their choices.

9. Nahéma Ricci as Antoneta

Canadian actress Ricci (born 1995) stunned in Antigone (2020), winning Best Actress at Prix Iris. Also appeared in Viking and Transplant. Antoneta’s name suggests European intrigue. Ricci’s ethereal intensity hints at a mysterious outsider who further complicates the group’s dynamics.

10. Tyrone Benskin as Dr. Ott

Veteran actor Benskin appeared in Coroner, *19-2*, and The Umbrella Academy. Extensive theater work includes Shakespearean roles. As Dr. Ott, Benskin likely plays an authority figure – therapist, lawyer, or mediator – injecting sobering reality into the emotional freefall.
