The actress, who reprises her role as ELENA in sequel The Legend of Zorro, admits she was initially baffled when news crews would try and interview her in a foreign tongue, but she quickly realised they thought she was a Latina.
She recalls, "The first time I walked on a red carpet they were, 'Hola Catherina.' I was like, 'Si, si, gracias.'
"It was a compliment that they thought my accent was convincing. But I'm Welsh, through and through."
