While some actors come from artistic and creative families, Alexander is the product of academic parents. The "Glasshouse" actor explained to Spindle Magazine, "I come from a normal, loving family – predominantly made up of academics, so it was always funny to me that all I wanted to do was the exact opposite of what my family did. I hate the idea of working a 9-5 office job, even though I find my parents inspiring, and have basically always been drawn to the weird, confusing, difficult things that demand creativity and a vast imagination."
