Karen Gillan is reminiscing about her earliest years in the film industry.
The Scottish actress celebrated her 34th birthday on Sunday by sharing a throwback clip from her "real directorial debut" in a homemade horror movie she helmed at 13 years old. Gillan also played the killer in the scene, while her dad portrayed one of her victims.
"To celebrate my birthday I thought I'd share this little teaser for a horror film I made when I was 13 years old. My real directorial debut," she wrote in the caption.
"I made my dad act in the film and made @donnatello876 my trusty camera operator," Gillan wrote. "I will post the full video if I can get my Dad to agree to let me share. For some BAFFLING reason he seems reluctant for people to see it…"
"Featuring some of the worst acting you'll ever see but some of the BEST wallpaper you'll ever clap eyes on. Swipe for the gruesome ending. Thinking about submitting this to @sundanceorg. You think it'll get in? Enjoy. Try not to get too scared. #daddydaddydaddy."
Gillan's sophomore directorial outing (previously reported as her debut) came in 2018 with The Party's Just Beginning, which she also wrote and starred in. Set in her native Inverness, Scotland, she played Liusaidh, who goes through a downward spiral following the death of a friend by suicide.

The Guardians of the Galaxy actress previously told PEOPLE about the "very interesting experience" of directing herself in a film for the first time.
"Normally, I'm so used to having a collaborative focus where I can turn to someone for reassurance or bounce ideas or have conversations before trying it out," she explained in December 2018. "It's ridiculous. I would give myself four or five options and then I would construct the performance and the edit."
