Landing high-profile guest stars to populate the world of Quinta Brunson’s “Abbott Elementary” became considerably easier for casting director Wendy O’Brien, who won an Emmy in 2022, as the ABC comedy’s popularity skyrocketed in the last three years. But juggling the flurry of cameo requests for Season 3 came with its own set of unique challenges — one O’Brien welcomed.
“In Season 1, nobody knew who we were,” she said. “In Season 2, the pulse of the show kept getting bigger and wider. In Season 3, it was unbelievable the people who were pitched to me and, I can only imagine, to Quinta.”
