Notable Icelanders who have an inherited family name include former prime minister Geir Haarde, football star Eiður Smári Guðjohnsen, entrepreneur Magnús Scheving, film director Baltasar Kormákur Samper, actress Anita Briem and member of parliament (and former news reporter) Elín Hirst. Before 1925, it was legal to adopt new family names; one Icelander to do so was the Nobel Prize-winning author Halldór Laxness, while another author, Einar Hjörleifsson and his brothers all chose the family name ``Kvaran''. Since 1925, one cannot adopt a family name unless one explicitly has a legal right to do so through inheritance. (The law was amended in 1991 and 1996.)
