Diane grew up in Derbyshire where her abiding passion for horses first developed, moving to London to attend RADA. Whilst undertaking a clutch of serious classical roles in her early career she harboured a secret desire to be Goldie Hawn and had the lure of the bright lights not won out then a career in astrophysics undoubtedly beckoned.
