During the production of her episodes, Williams recorded several impromptu interviews and behind-the-scenes candid footage on her smartphone camera, which were later uploaded by the BBC under the title #maisiecam. Several of these (though not all) were included in the Complete Series Nine DVD/Blu-ray set as part of the Sublime Online package.
According to comments made by her in the Doctor Who Extra installment devoted to Face the Raven, at the time she filmed The Girl Who Died and The Woman Who Lived, Williams was not aware that she was going to be asked back to reprise Ashildr/Me a few months later for Face the Raven and Hell Bent.
