Alex Kapp Horner and Tricia O’Kelley never knew each other before they met at a read-through on the set of CBS comedy “The New Adventures of Old Christine.”
But their uncanny onscreen rapport belies that fact. With a witty, perfectly timed rapport, the pair give the impression of a vaudeville team with decades of experience.
Both play wealthy, snooty mothers — Lindsay and Marly, respectively — at a hoity-toity private school who look down on Julia Louis-Dreyfus’ down-to-earth Christine.
Horner had a seemingly inconsequential connection to Dreyfus before coming in for an audition. She had played George’s girlfriend who refuses to break up with him on an episode of “Seinfeld,” the series that made Dreyfus a worldwide star.
“I remember telling her, ‘I did an episode and I know you did one, too,” Horner joked to Drefyus.
She also had a small role on “Maggie Winters,” a show exec produced by “Christine” creator Kari Lizer that had a short run on CBS in the late ’90s.
After both Horner and O’Kelley auditioned, neither knew what to expect, though they felt it had gone well.
“A few days later we got a call asking if we wanted to be regulars,” reflects Horner. “It was like pennies from heaven.”
