Margaret John's first public appearances were at Swansea's
Grand Theatre, where she had small parts in weekly repertoire. Not being a fluent
Welsh speaker, she found Welsh language productions challenging. In September 2009, John appeared in the graphic short film
Cow by director Peter Watkins Hughes warning of the dangers of texting while driving. Also in 2009, John appeared in
The Vagina Monologues; prior to that, she had not been on stage since the 1980s, when she appeared in
Medea at London's
Young Vic Theatre, with Dame
Eileen Atkins. John subsequently appeared on stage in
Calendar Girls at the Wales Millennium Centre from 27 July to 7 August 2010 and at
Venue Cymru,
Llandudno, from 9 to 14 August 2010, alongside fellow Welsh actress
Ruth Madoc. She also starred in the 2009 film
A Bit of Tom Jones?. In March 2010, she appeared in the
BBC One Wales programme
Margaret John – National Treasure, which featured clips from the last 50 years of television and special guest interviews with, among others,
Ruth Jones,
Eve Myles and
Joanna Page. The programme was broadcast again, in tribute to John, on 5 February 2011. She also featured in a short BBC video in which she cooked
Welsh cakes for
St. David's Day. Her last appearance on screen, broadcast after her death, was in
Game of Thrones as Old Nan. ==Personal life==
