Tiago Martinez

Biography

Tiago Martinez is a rising star in the "New Hollywood" youth circuit, known for bringing a natural, grounded energy to high-stakes sci-fi and animation. A Los Angeles native, he began his career with guest spots on NCIS before landing his breakout role as Javier Diaz in the Apple TV+ alternate-history epic For All Mankind. While he was eventually succeeded in the role by Santiago Veizaga as the character aged, his performance as the young son of Aleida Rosales made him a face to watch in the prestige streaming space. To be honest, 2025 and 2026 have been his most transformative years yet. He officially joined the "Dora Cinematic Universe" as young Diego Márquez in Dora and the Search for Sol Dorado, proving he can handle a major franchise. However, it’s his work in animation that is currently putting him on the global map. After providing voice work for the 2024 hit The Wild Robot, he was cast in the lead human role of Sebastian in Warner Bros.' 2026 animated reboot of The Cat in the Hat. Starring alongside Bill Hader and Xochitl Gomez, Tiago plays the younger brother who, along with his sister Gabby, becomes a "client" of the Cat’s chaotic but well-meaning intervention.
