The Good Daughter is drawing attention for one reason above all: Brendan Gleeson has the best part, and he takes it. In the six-part Georgia thriller, he plays Rusty Quinn, the broken father of two lawyer daughters, and every scene seems to bend toward him.
That is why people are searching for The Good Daughter cast now. The series is adapted by Karin Slaughter from her standalone 2017 bestseller, but the immediate hook is Gleeson’s turn, not the familiar shape of the material. He is seen flumped on a toilet in a novelty clown nose, and later he mutters, “I just farted.” The performance is broad, sly and weirdly magnetic, which fits a show that opens at full volume.
Within its first 15 minutes, the series piles on a horrifying family tragedy, a school shooting, police brutality, a vulnerable teenage suspect, Charlie cheating on her estranged husband with a man with a ponytail, a comically evil DA in an oversized white Stetson and even a racoon called Henry. The scale of that opening gives the show a hard, frantic pulse, and Gleeson keeps finding the off-kilter notes inside it. He is the kind of actor who can make a line like “Why is ma laaahf filled with contrary feee-males?” sound like both a joke and a warning.
Rose Byrne plays Sam and Meghann Fahy plays Charlie, the two headstrong lawyer sisters who are supposed to carry the emotional and legal fight. But they are given very little to do compared with Gleeson, and that imbalance matters because the series is meant to be as much about the daughters as the damaged father. Byrne, a Golden Globe winner, has the steadier line readings, while Fahy gets the sharper bite, including “This is all bullshit” and “You’re a dipshit,” but neither is allowed to dominate the way Rusty Quinn does.
That split is also what gives the show its odd shape. The flashbacks, set in the 90s, move back into the family home, where a pair of leering locals burst in, the beloved poetry-quotin' mom is killed, and Sam and Charlie are left to absorb the damage. The present-day story then turns the sisters loose on the local cops, who are challenged at every step, and the result has the rough, small-town secrecy of a Harlan Coben adaptation.
So the answer to the casting question is clear: this is Brendan Gleeson’s show first. The rest of The Good Daughter cast gives the series its framework, but Rusty Quinn gives it its pulse, its joke and its menace. If the adaptation has a weakness, it is that the daughters are held back just when their story should be taking over.
