Tatum is a British-Canadian actor whose professional career began aged 11, playing Susan in White Christmas at The Dominion Theatre. Many influences and interests, before and since that debut, led her to OSD, most notably Tring Park School for the Performing Arts. Whilst there, she won the prestigious Acting Cup in her final year. Tatum possesses great physical prowess, having received training in ballet, tap, and jazz, alongside various sporting accolades and a gymnastic ability that stems from her Mother. Her Dad, a gigging lead guitarist, likes to think he gave her natural rhythm and the A-Z of proper music (Arctic Monkeys – Ziggy Stardust). She loves the outdoors, from Britain to British Columbia, and any activity on a mountain.
