From Tardis Wiki, the free Doctor Who reference
Jemima Rooper (born 24 October 1981[1]) voiced several characters for Big Finish Productions including the Eighth Doctor's companion Izzy Sinclair.
Rooper's performance as Izzy was praised by Alan Barnes, creator of the character and writer of Izzy's Story. Barnes said "she 'got' the character the second she spoke her first line, absolutely - walking the line between 'utterly adorable, give her a hug' and 'slightly irritating nerd' like she was born to play it!"
