Jason Earles plays Miley's brother Jackson on "Hannah Montana." Jackson and Miley do not always see eye to eye and often bump heads, but they ultimately share love and appreciation for each other. While this might sound sweet and wholesome — two teenage siblings getting along — there is one detail about Earles that actually might make the whole situation seem a little uncomfortable.
When "Hannah Montana" first aired in 2006, Cyrus was 13 years old, and so was the character she played. However, when Earles first started playing Jackson, who was 15 in the show, the actor was 28 years old (per Insider). The show aired for four seasons from 2006 to 2011, which means that Earles continued to play Jackson well into his 30s.
It's not technically unusual for actors to play characters who aren't same age as themselves. If actors only played people of the same age, it would be quite difficult to find work. Nonetheless, a grown adult actor playing a minor character about 13 years younger than him is a bit unsettling.
