Chariots of Fire (2012) - Florence Mackenzie
Antonia played the role of Florence Mackenzie in the 2012 stage adaptation of "Chariots of Fire" on the West End.
Chariots of Fire is based off the true story of Eric Liddell and Harold Abrahams, British athletes who competed in the 1924 Olympics. Antonia portrayed Eric Liddell's fiancée Florence Mackenzie, a new addition to the stage adaptation.
This was a musical and involved the actors running around the stage and venue throughout the performance, requiring the cast to train extensively to be physically capable of bursting into song mid-sprint. Based off the timing and location, I'm pretty sure this is the performance Antonia discussed in a voice sample on her voice acting agency page that she once had to do with a bike lock stuck around her waist too 😂
