Actor Matthew Rhys says he speaks only in Welsh to his US-born young son in the hope he will understand the language for life.
Cardiff-born Rhys, 44, who lives in New York with his family, joked he plans to "force" him to embrace Welsh culture.He and partner Keri Russell had Sam, two, after meeting on the set of The Americans in 2013.
"I speak to him solely in Welsh," he told the Radio Times. "He can answer and understand at the moment."
In September, Rhys's own accent surprised fans who took to Twitter expressing shock at hearing his native tones after he gave a speech to accept an Emmy for his role in the Cold War drama.
