Liz Carr studied Law at the University of Nottingham. She was in her thirties when she took on her first professional acting role playing Mother Courage before heading to the Young Vic theatre with another Brecht play, The Exception and The Rule. Since then her acting, stand-up, cabaret and campaigning have taken her all over the world. In 2013, she joined the long-running BBC crime thriller series Silent Witness as regular character Clarissa Mullery.
Liz has premiered her show Assisted Suicide: The Musical to sell-out audiences at the Royal Festival Hall in London. She toured it nationally and internationally in 2017. She co-hosted the Royal Television Society Award winning BBC Ouch! podcast for seven years and made a BBC World Service documentary When Assisted Death is Legal.
For the past 20 years, Carr has been a disability rights campaigner in the UK and has spoken at many rallies. In May 2008 she joined with ADAPT, a prominent disability rights group in the United States, to raise money for ADAPT and to protest against presidential candidate John McCain's refusal to support the right of people with disabilities to live in their own homes.
In 2011, Carr was part of a Newsnight debate on assisted suicide following the screening on the BBC of Terry Pratchett: Choosing to Die. She opposes Lord Faulkner's Assisted Dying Bill, stating: "I fear we’ve so devalued certain groups of people – ill people, disabled people, older people – that I don’t think it’s in their best interests to enshrine in law the right of doctors to kill certain people."
