Rhys discusses the self-doubt behind his career, including why he once declined Hamlet and how his RADA training gave him practical tools for approaching demanding roles. He explains how actors can make strange or disturbing scenarios emotionally truthful by pursuing clear objectives, and why morally conflicted characters often appeal to him. His work on Girls becomes a case study in using rehearsal and precise writing to explore manipulation, consent, and abuse. The conversation then turns to the ways personal relationships and cultural identity influence his performances. Rhys describes drawing on real arguments with Keri Russell, the impact of Welsh pessimism on his outlook, and the significance of language and accent in Welsh identity. He also reflects on falling in love with Russell while working together and the challenge of combining partnership, parenthood, and two acting careers. Even after professional recognition, he remains motivated by uncertainty, rejection, and the desire to keep pursuing difficult, meaningful work.
