“The Princess”, currently streaming on Hulu, is basically an extended fight sequence: Joey King, the titular heroine, can only escape her prison tower by battling through an army of mercenaries. Now imagine filming those scenes — out of order — over a period of 12 weeks, and you have an inkling of the challenge faced by the Hair and Makeup Designer Lynda Armstrong. Lynda speaks with me about the pleasure of working with Joey and the difficulty of getting hair products delivered from London to Bulgaria in a timely fashion (thanks, Brexit).
