To Catch a Cheater Cast Guide

The cast of “To Catch a Cheater” is deliberately built around two generations. Kate Watson leads the movie as Monica, whose daughter Hannah dies shortly after becoming involved in a loyalty test with her friends Megan and Charli. Philip Boyd plays David, Monica’s estranged husband, while Sheila Leason and Jessie Pettit portray Bridget and Kim, the two women whose friendship with Monica stretches back to when their daughters were born. Jordan Kennedy, Lily Bowen and Valentina Rivas play the younger trio. The relationships matter because this is not a mystery filled with random suspects. Almost everyone Monica investigates is already part of a family she thought she understood.

This guide explains the major characters without revealing the movie’s final killer.

Who Does Kate Watson Play?

Kate Watson stars as Monica Jackson, Hannah’s mother and the character through whom most of the mystery is experienced. Monica refuses to accept the initial explanation for Hannah’s death and begins reconstructing the teenager’s final days, even when her family, friends and the authorities worry that grief is influencing her judgment. Watson said she was drawn to the role because of the emotional circumstances surrounding a mother trying to process a child’s death, and she approached Monica’s grief physically rather than trying to imitate a personal experience she had never lived through.

Watson has become a recognizable face in television thrillers, particularly Lifetime productions. Her recent credits include “Secret Life of the Dean’s Wife,” “Murder at the Derby” and “Who’s Stalking My Family?,” while earlier work includes “Killer Advice,” “Deadly Infidelity” and “Bridge of the Doomed.” “To Catch a Cheater” gives her considerably more emotional weight than a standard suspicious-wife role because Monica is investigating while simultaneously trying to understand how well she really knew her daughter.

Philip Boyd Plays David

Philip Boyd plays David, Monica’s estranged husband and Hannah’s father. David returns after Hannah’s death, bringing an already complicated relationship with Monica back into the same house at the worst possible time. Their grief does not immediately erase the problems that separated them, and part of Boyd’s job is showing a father who wants answers while responding differently from Monica to the pressure surrounding the investigation.

Boyd has a long television resume and is especially familiar as Oscar in Tyler Perry’s “The Haves and the Have Nots.” His credits also include “Feud,” “General Hospital,” “The Young and the Restless” and the CBS soap “Beyond the Gates.” That experience with serialized drama suits David, who spends much of the movie caught between family history and a mystery that keeps changing shape.

Sheila Leason and Jessie Pettit Play Monica’s Closest Friends

Sheila Leason plays Bridget Lewis, while Jessie Pettit portrays Kim, the two women closest to Monica before Hannah’s death begins putting their friendship under pressure. The three mothers have known each other since their daughters were born on the same day, giving their bond a history that predates the murder mystery by nearly 18 years. Bridget is Charli’s mother, while Kim is Megan’s mother, so the parents’ friendships and the teenagers’ friendships overlap almost completely.

Bridget and Kim also share a business venture, which adds another layer of loyalty and financial pressure to their relationship. Leason is a Miami-born actress, dancer and stunt performer whose credits include “Pitchfork” and “Kiss of Death.” Pettit appeared in the Laurel and Hardy biopic “Stan & Ollie” and has also worked as an actress, producer and writer. Their characters are important precisely because Monica does not approach either woman as a stranger she can casually suspect.

Jordan Kennedy Plays Hannah

Jordan Kennedy portrays Hannah Wilson, Monica and David’s teenage daughter. Hannah does not simply function as the unseen victim whose death starts the plot. The film spends time with her before the tragedy, showing her relationships with Megan and Charli and her discomfort with the loyalty-test prank they agree to carry out involving their boyfriends. That material becomes essential because Monica later has to reconstruct events the audience has only partially witnessed.

Kennedy has appeared on “Will Trent” and “Swagger,” and her recent credits also include “The Shards.” She has limited screen time compared with Watson, but Hannah needs enough personality to make Monica’s investigation about more than solving a puzzle. The role has to establish a daughter with friendships, romantic problems and pressures her mother did not fully see.

Who Plays Megan and Charli?

Lily Bowen plays Megan, while Valentina Rivas plays Charli, Hannah’s two closest friends. The trio become involved in the cheating test that gives the movie its title, with the teenagers attempting to discover whether their boyfriends will flirt with another member of the group. Megan is more hesitant about the increasingly reckless behavior, while Charli is the stronger personality pushing the prank forward. Their different reactions become important once Hannah is gone and Monica starts asking what the girls knew.

Bowen is also a singer-songwriter and voice performer in addition to her screen acting work. Her professional resume lists “To Catch a Cheater” as a supporting Lifetime role. Rivas, meanwhile, has credits including the 2023 project “Pantser.” Neither actress is present simply to populate Hannah’s school scenes, since Megan and Charli hold pieces of the timeline Monica desperately needs to understand.

Who Else Is in the Cast?

Roy Lynam plays Doug, Kim’s husband, whose connections to the other families become increasingly relevant as Monica investigates. Steven McCormack portrays Leo, Hannah’s older brother, while Luke Omalza plays Hunter, Hannah’s boyfriend. Christian Shupe appears as Nick, another teenager connected to the loyalty-test storyline. Lauren Madigan is credited as Mrs. Whitmore, and Francois Larosa appears as a birthday-party guest.

Omalza previously appeared in “The Girl Who Believes in Miracles,” while McCormack has accumulated a growing collection of television and feature credits. The supporting actors matter because Romay’s mystery works by repeatedly moving suspicion from one relationship to another rather than introducing an obvious outsider. Even minor characters can hold information that changes how Monica interprets Hannah’s final day.

The smartest part of the casting is therefore its interconnectedness. Watson may carry the film, but Monica’s grief only becomes a mystery because nearly every answer leads back to someone she already knows. Parents, children, spouses and friends are all connected long before the investigation begins. “To Catch a Cheater” is less about discovering a stranger hiding in the community than about Monica learning that familiarity never guaranteed honesty.
