Blackwood was born in Antrim in 2000.[1] She moved with her family to Inverness, Scotland when she was six years old and has lived there ever since.[1]
Blackwood played Alexis in the 2015 episode "Preparing the Weapon" of the crowdfunded[3] TV series Cops and Monsters.[4] In 2018 she appeared in a short film called Sundown directed by Ryan Hendrick.[5]
She played the young Amelia Pond in several Doctor Who episodes; "The Eleventh Hour", "The Big Bang", "Let's Kill Hitler", and "The God Complex", with footage of her briefly reused in "The Angels Take Manhattan". She is the cousin of Karen Gillan, who portrayed the adult Amy Pond, although they had never met before Blackwood was cast.[6] Resemblance to Gillan was a factor in her casting.[7][8] In 2018, she starred in Sundown, an award-winning short film by Ryan Hendrick. In 2020, she played Amy Pond in the Doctor Who short: "The Raggedy Doctor by Amelia Pond".[9]
