Recalling her childhood, Clarke says she didn’t grow up wealthy and her parents struggled financially at times:
My dad was a sound designer. He worked on productions of “West Side Story” and “Chicago” in the West End. My mother was, and is, a businesswoman, the vice-president of marketing for a global management consultancy. We weren’t wealthy, but my brother and I went to private schools. Our parents, who wanted everything for us, struggled to keep up with the fees.
