We first came across Cush's acting in 2010's British lesbian drama Lip Service, where she played Becky Love. Before that, she was part of Torchwoods main cast, and even appeared on the series My Family and Harley Street.

In 2015, she became a regular cast member on The Good Wife, and played a bar court attorney who develops a close friendship and business partnership with protagonist Alicia Florrick (Julianna Margulies).

After that show came to a messy end, she continued playing Lucca in The Good Fight spinoff, this time as one of the series' leads.

In Season 3, we tracked Lucca's pregnancy with U.S. congressman Colin Morello (Justin Bartha), and it turns out the actress was pregnant in real life as well.
