Graduating from the Masters Performing Arts College in 2010, she has undertaken a number of theatrical roles, including productions for M&M Theatrical Productions, and also touring in Italy in Circus for the Smile Theatre Company. Breaking into television, as well as An Adventure in Space and Time, she has just played a supporting actress in the series premiere of this year's Poirot - Elephants Can Remember.
Holt joins Jamie Glover (William Russell/Ian), Jemma Powell (Jacqueline Hill/Barbara) and Claudia Grant (Carole Ann Ford/Susan) in portraying the actors who accompanied the First Doctor on his adventures. As previously reported, Peter Purves (Steven) has indicated that he would be represented in the drama, too, and that an actress playing Maureen O'Brien (Vicki) was believed to have been spotted during filming at BBC Television Centre.
Also joining the family of supporting actors is John Foreman, who plays a "passerby/interviewee".

The cast and crew have been huddled away in studio for the week, with Sacha Dhawan (Waris Hussein) summarising his wait between takes: "Dressing room boredom..."
Filming is expected to wrap next week.
One person with some free time next week will be Brian Cox (Sydney Newman); the actor is due to be a guest on Wednesday's edition of The Wright Stuff next week. The show is broadcast weekday mornings on Channel 5.
