Zeta-Jones takes a lesson in Welsh

Actress Catherine Zeta-Jones had to perfect her old accent for a new mountain climbing documentary after producers told her she didn't sound Welsh enough.

A Mountain to Climb producer John Morgan felt the Oscar winner had developed too much of a Hollywood tone and asked her to chat to her father over the phone in an effort to regain the accent she grew with in Swansea.

Morgan said: "When I met her she was making a film where she had an American accent, so you could here it in her voice. We made sure that when we went to record her she had the full Welsh treatment.

"We encouraged her to talk to her dad on the phone too. The end result sounds wonderful."

Morgan's new movie, which is narrated by Zeta-Jones, follows a charity celebrity hike up Africa's Mount Kilimanjaro by Welsh celebrities.
