Guillory explained that she "became an actor because I wanted to know what it was like to be other people. Because possibly I don't like myself", and later said "I hate acting, really hate it. I kind of fell into it sideways ... I started acting because I got offered a job when I was 16, and they wanted to pay me £8,000, and we'd always lived on Family Support". She went on to say that her frustration with later film roles left her bitter, but after seeing Helen Mirren on stage she was inspired again.
