Laura was working as a receptionist between theatre jobs when she was asked to read for a role for Downton Abbey. She was waiting to find out if she would be going to Dubai to appear in a stage production of Shakespeare's "Twelfth Night", but turned it down to wait for Downton Abbey. Everyone told her to not get her hopes up, but she got a call back and then a few days later was told that she had the part.
She starred in the historical drama The Spanish Princess alongside Downton cast-member Harriet Walter.
- Like Edith, Laura is the middle of three sisters.
- Laura had a minor role in the film Tinker Tailor Soldier Spy.
