Photos have been released showing the cast of The Christmasaurus in rehearsals ahead of the show's opening night.
Carrie Hope Fletcher, Matt Willis, Harry Judd, Tom Fletcher and Giovanna Fletcher will all star in the piece, directed by Derek Bond and adapted for the stage by Miranda Larson. The show will feature sleigh bells, dancing elves and a special appearance from Saint Nick.
The musical is based on the 2016 novel of the same name, written by Tom Fletcher and nominated for the Children's Book of the Year at the British Book Awards. The show follows the life of young boy William Trundle as he embarks on adventures across the North Pole.
Fletcher has also announced that The Christmasaurus will be adapted into an animated feature film, directed by Michael Gracey (who makes his directorial debut with The Greatest Showman which opens this Christmas and stars Hugh Jackman and Zac Efron).
The Christmasaurus runs at the Eventim Apollo Hammersmith from 21 to 28 December.
