Biography
Mason Thames (/θeɪmz/, born July 10, 2007) is a rising young actor who made a remarkable debut as the young teen lead in director/co-writer/producer Scott Derrickson’s hit horror movie, The Black Phone (2021), based on Joe Hill’s short story, co-starring Madeleine McGraw, Jeremy Davies, James Ransone and Ethan Hawke, and returning a spectacular gross of over $161 million (ten times costs) for Blumhouse Productions/Universal Pictures.
Thames had his second starring role in his second theatrical feature with the David Henrie-directed adventure horror movie, Monster Summer (2024), co-starring Mel Gibson, Lorraine Bracco, Nora Zehetner, and Kevin James, and released wide by Pastime Pictures. Thames landed his biggest starring role to date as Hiccup Horrendous Haddock III in director/writer/producer Dean DeBlois’ live-action adaptation of his original animated feature, How To Train Your Dragon (2025)—which itself was based on Cressida Cowell’s book series—co-starring Nico Parker, Gerard Butler, Nick Frost, Bronwyn James and Harry Trevaldwyn and released by Universal Pictures.
Thames co-starred with McKenna Grace, Allison Williams, and Dave Franco in the Josh Boone-directed screen version of Colleen Hoover’s novel, Regretting You (2025), produced by Constantin Film and released by Paramount Pictures. Mason Thames revived his role as Finney in director/co-writer/producer Scott Derrickson’s anticipated sequel, The Black Phone 2 (2025), co-starring Ethan Hawke, Jeremy Davies, Madeleine McGraw, Demian Bichir, and again produced by Blumhouse Productions and released by Universal Pictures.
Thames reunited with co-star McKenna Grace in director/writer Lee Kirk’s road comedy, New Year’s Rev (date to be announced), with Jenna Fischer, Sean Gunn, Fred Armisen, Bobby Lee, Jolene Blalock, Angela Kinsey, Keen Ruffalo, Ignacio Diaz-Silverio, Buffy Milner, and Billie Joe Armstrong, and produced by Live Nation Productions. Thames then returned as Finney in Universal Pictures’ live-action sequel, directed and written once again by Dean DeBlois, How to Train Your Dragon 2 (2027), co-starring Gerard Butler and Nico Parker.
Thames co-starred in the Germany-U.S. co-production based on Colleen Hoover’s novel, Regretting You (2025), co-starring Allison Williams, McKenna Grace, Dave Franco, and Willa Fitzgerald under Josh Boone’s direction, and which was released by Paramount Pictures (worldwide)/Constantin Film (Germany).
Thames then co-starred with Peter Dinklage and Dave Franco, with Kiernan Shipka and O’Shea Jackson, in director/co-writer/producer Macon Blair’s comedy, The Shitheads (date to be announced), and was produced by Gramercy Park Media/Rough House Pictures/Slate Entertainment Group. Thames returned to his live-action role as Hiccup alongside the original cast in director/writer/producer Dean DeBlois’ sequel for Universal Pictures, How to Train Your Dragon 2 (2027).
