Tiago Martinez’s Early Emergence Across Screen and Studio
Few performers break into both live-action television and animated voice work before reaching their teenage years, yet Tiago Martinez has done exactly that. A young American actor credited on IMDb under the fuller name Tiago Martinez Castillo, he first appeared on screens with a guest role on NCIS in 2021 and quickly built a track record that spans prestige drama, animated features, and major franchise film.
The Wild Robot and the Voice Work That Followed
Landing a voice role in DreamWorks Animation’s critically acclaimed *The Wild Robot* (2024) placed Martinez in one of the most celebrated animated releases of that year. Cast as Baby Opossum 2 alongside a voice ensemble anchored by Lupita Nyong’o, the credit marked his entry into studio animation. That momentum carried directly into development on *The Cat in the Hat* (2026), where he voices the character Sebastian – a production still in post-production that signals continued demand for his work in the booth.
For All Mankind and the Live-Action Foundation
His four-episode run as Javier Diaz in Apple TV+’s alt-history drama *For All Mankind* (2022) gave Martinez his first sustained dramatic platform. The role, requiring him to hold his own in a prestige ensemble built around career veterans, earned him wider industry notice. Around the same time, appearances on *Send Help* and a segment on *Jimmy Kimmel Live!* rounded out a period of rapid expansion across formats.
Dora and the Search for Sol Dorado
Playing Young Diego in the 2025 Paramount+ live-action feature *Dora and the Search for Sol Dorado* connected Martinez to one of Nickelodeon’s most enduring properties. The film extended the universe established by the 2019 *Dora and the Lost City of Gold*, and his portrayal of Diego’s younger self brought a grounding of sincerity to the franchise’s mythology. With *Busboys* also in post-production as of 2026, the pipeline of upcoming work reflects a young career gathering real pace.
