As one of the original “Billy’s” in BILLY ELLIOT, Dean has been working from a young age but it was HBO’s hit series GAME OF THRONES, playing the ill-fated King Tommen Baratheon that first gave him international notice. Other credits include Rowan Joffe’s BEFORE I GO TO SLEEP with Nicole Kidman, Colin Firth and Mark Strong, E4’s critically acclaimed series, GLUE and David Michod’s THE KING with Joel Edgerton and Timothee Chalamet for Netflix which had its premiere at Venice. Dean was the co-lead in Sam Mendes’s sensational 1917 from producer Steven Spielberg which won, amongst many other accolades, the Golden Globe for Best Film, 7 BAFTAS including Best Film and Best British Film and 3 Academy Awards.
Dean has most recently been seen in Lena Dunham’s CATHERINE CALLED BIRDY for Working Title and Amazon opposite Andrew Scott and Billie Piper and THE WALK-IN for ITV opposite Stephen Graham. His next projects are the animated feature, OZI, from Appian Way opposite Amandla Stenberg and Donald Sutherland and Bad Robot’s THE ACOLYTE for Disney+.
