He was a swimmer and powerlifter, winning first place in the Orlando Open Championships in 2022 with a bench of 170 and a deadlift of 211. Sorry, I couldn't find any powerlifting photos.
He was also very busy with Hebrew School and temple activities. It's a wonder that he had time to go on auditions.
Jackson's on-screen acting credits begin with a series of shorts: Show and Tell (2013), Birthday Boy (2014), Table Manners (2015). He starred with Michael Berthold, Stacy on The Righteous Gemstones, in Dear Ones (2014), On Your Street (2016), and Ranger Things (2017).
Plus walk-ons in Tomorrowland (2015) with George Clooney, Modern Family (2016) with Mitch dressed as Little Orphan Annie, and Miss Peregrine's Home for Peculiar Children (2016), with Asa Butterfield
Jackson's first starring role came in Schoolbus Diaries (2016-17), with "the everyday lives of children and teenagers" mediated by their surprisingly wise bus driver.
No Place in the World (2017) is a Christian movie featuring two sisters with problems at home and school, "trying to survive in a disconnected, self-centered world." I'll bet they find God. Jackson seems to play a school shooter.
I can't find the tv series Mohawk (2018) streaming anywhere, but Jackson's demo reel shows his father, who has just crucified someone, punching and strangling him. He's saved by the spirit of a Native American woman.
