Josh Hutcherson was about 15 years old when he filmed and released Journey to the Center of the Earth (2008).

How that age is calculated

  • Josh Hutcherson was born on October 12, 1992.
  • Journey to the Center of the Earth 3D came out in July 2008 in theaters.
  • That means during the movie’s release and promotion in mid‑2008, he was 15 years old and turned 16 a few months later in October 2008.

So when people talk about “how old was Josh Hutcherson in Journey to the Center of the Earth ,” they are referring to his mid‑teen years—roughly age 15 during the time of release and late production.
