Louis Partridge was 22 when Enola Holmes 3 was filmed, based on his birth date of June 3, 2003 and the film’s production wrapping in 2025.

Quick math

  • Born: June 3, 2003.
  • Filming wrapped in 2025.
  • That puts him at 21 or 22 during filming, depending on the exact shoot dates; the safest single-age answer is 22.

Tiny nuance

If most filming happened before his June 3 birthday in 2025, he would have been 21 for part of production. If it happened after that birthday, he was 22 throughout that period.
