Rush, the latest scripted offering in USA's move to edgier fare, centers on Dr. William Rush (Ellis), a hard-partying “medical fixer” who privately caters to L.A.’s elite and oftentimes less-than-squeaky clients. But his services come with a hefty price tag.
Hamlin, who recurred on Mad Men, has been cast as Rush's estranged father, Warren, a retired doctor who has been a controlling, domineering and judgmental presence in his son's life. Warren has since remarried and started a new family, but the old dynamics that drove him and Rush apart remain intact.
Nichols will play Warren's much younger "trophy wife," Corrine Rush -- pretty, attentive and supportive, she is everything you want in a spouse. Though she appears to have it all together, she's hiding her own demons beneath the facade: She thinks the life she has is what she wants, but in truth, she's yearning for something more.
