Jackson also has a central role in the feature film Hannah Montana: The Movie.Despite portraying a teen, Jason Earles was in his late twenties when he started the show. Like the rest of his family, Jackson is from Tennessee.
Later, in "My Boyfriend's Jackson and There's Gonna Be Trouble" a paparazzi follows Miley and Jackson home from a concert and reports that they are dating.Unlike his father and sister, Jackson seems to have no musical talent.Even his own mother admitted that he sings like "a regular tone deaf walrus." During Miley's nightmare in "I Am Hannah, Hear Me Croak" he becomes a rock-star sensation named Bucky Kentucky. In "Debt It Be" he plays an old woman at a rest home, in "You Give Lunch a Bad Name" he plays a pot-bellied health inspector, and in "Knock Knock Knockin' on Jackson's Head" he gives a believable performance of having suffered amnesia.Jackson and Miley constantly bicker and compete for their father's approval.Miley often finds Jackson's antics disgusting and Jackson thinks Miley is too full of herself sometimes.
When Jackson first attended school in California he was made fun of because of his accent, cowboy hat, boots, and large belt buckle with shining bright lights which he wore to school. Also he has a limited amount of friends, only showing two: Cooper & Thor.
