Kellan Tetlow is a grounded young actor known for his quiet emotional presence, natural stillness, and instinctive listening - qualities that have landed him roles across film, TV, voiceover, and international markets. He made his film debut in The Saint of the Impossible, which earned multiple international festival awards, and by age six, was cast as Young Nicky - Justin Hartley's son - on NBC's This Is Us. That same year, he joined FX's A Murder at the End of the World as a series regular, acting opposite Clive Owen, Harris Dickinson, and Emma Corrin. At eight, he booked a guest star on FBI: International and was selected for a chemistry read with Billy Crystal for Apple TV's Before. Internationally, Kellan starred in a 48-episode Korean sitcom as the lead, before returning to the U.S. and booking national commercials for Chrysler, Credit One, and Dish Network, along with regional spots, music videos, and print. His voiceover work includes credits for Disney, Nickelodeon, PBS, Warner Bros., and more. In 2025, he voiced a lead in a top-secret animated feature directed by an Oscar winner, brought Daniel Tiger to life for a major toy franchise, and wrapped a feature film opposite Lorraine Bracco and Leah Remini. He also recorded a lead role in a Japanese anime feature directed by Yoko Kono and Nobuhiro Yamashita, and will soon appear in an original live-action comedy for Paramount, directed by Trey Parker and Matt Stone. Behind the scenes, Kellan has been in high demand for studio and network recording sessions throughout 2024 and 2025, contributing to projects for AppleTV, Hulu, Disney, Netflix, DreamWorks, Paramount, and Universal. His looping and ADR work already spans major motion pictures and critically acclaimed streaming hits, where his quick wit and sharp improv instincts have made him a go-to talent. When he isn't working, Kellan stays active with hip hop, soccer, surfing, and basketball. He also plays piano and enjoys hiking with his family. Kellan is represented by Rebel Creative Group, Osbrink, and Take 3 Talent.
