Ezra Miller was 27–28 years old during the main filming of The Flash (2023), born September 30, 1992, with principal production taking place from late 2021 into 2022.

Quick breakdown by timeline

When filming happened

  • Principal photography for The Flash began in late 2021 and wrapped in mid-2022 , after several years of delays and director changes.
  • Some additional work and reshoots occurred into early 2023 before the film’s June 2023 release, but the bulk of on-set action was in 2021–2022.

How to calculate Ezra’s age

  • Ezra Miller: born September 30, 1992.
  • If filming started around November–December 2021 :
    • From Sep 30, 1992 to Nov/Dec 2021 → 29 years old near their birthday, but most of late 2021 they were still 28.
  • If filming continued through 2022 :
    • By late 2022, after their September 30 birthday, they turned 30.
    • So during most of 2022 filming, they were 29 , and briefly 30 toward the end.

Many sources and fan discussions round this to “27–28” because:

  • Early prep and some shooting may have started just before their 29th birthday in late 2021.
  • Some accounts refer to the start of full production rather than the entire span.

So the most accurate answer is:

  • Main filming (2021–2022): Ezra was mostly 28–29 , briefly turning 30.
  • If you’re thinking of the earliest principal filming period: they were around 27–28 at the very start, quickly moving into 29.

Why the confusion

  • The film was in “development hell” for years; Ezra was first cast in the role around 2013–2014 , when they were 21–22 , but that’s not when filming happened.
  • News articles from 2022 say “At 29, Ezra Miller has become one of the movie industry’s most sought-after actors, including an upcoming starring role in the 2023 DC feature ‘The Flash’,” confirming they were 29 during the main production phase.

TL;DR

  • When they filmed The Flash (main production 2021–2022): Ezra Miller was 28–29 (turning 30 late in filming).
  • If you’re quoting the very start of principal filming: many people say 27–28 , but the more precise range is 28–29.
