Breaking Bad actress Anna Gunn is facing a new court battle with her ex-husband Alastair Duncan over child support for their two young daughters. The star split from the Scottish actor-turned-realtor in 2008, when the drug drama first premiered on U.S. TV, and their divorce was finalised in 2009. The former couple agreed that Gunn would only hand over funds to Duncan for a short amount of time to help cover the costs of raising their girls Ella Rose and Emma, but now he has filed new papers in a U.S. court seeking further child support payments. In the documents, obtained by editors at TMZ.com, Duncan claims his financial circumstances have significantly changed since the deal was struck and he now only makes $10,000 (£6,250)-a-month compared to what Gunn earned during the final season of Breaking Bad, in which she played the long-suffering onscreen wife of Bryan Cranston's character Walter White. During the last season of the show in 2013, she reportedly raked in more than $1 million (£625,000). Duncan highlights the actress' new TV show Gracepoint, a U.S. remake of British drama Broadchurch, and her upcoming role in Off Broadway play Sex With Strangers as proof that she can afford his latest financial request.
