To date, Sebastian (known as Bash to his friends) has made five feature films, "The Hippopotamus" (written by Stephen Fry), "Wonderwell" (with Carrie Fisher and Rita Ora), "I’ll Find You" (with Stellan Skarsgård and Adelaide Clemens), "Where is Ann Frank" (still in post-production) and "Horrible Histories The Movie" (in which he plays the lead role of Atti, which will be released in cinemas internationally in July 2019). Bash has also appeared in a number of TV shows including "Houdini and Doyle" (ITV, Fox) and "Penny Dreadful" (Sky Atlantic, Showtime) but is probably best known for playing Young Ned Stark in "Game of Thrones" (HBO).
He made his first professional appearance on stage at the age of 7, and went on to play numerous roles in the West End and on tour including Gavroche in "Les Misérables", Oliver in "Oliver The Musical", Tommy in "Matilda The Musical", and Adrian Mole in "The Secret Diary of Adrian Mole".
In addition to musicals he also made appearances in productions of "Coriolanus" at the Donmar Warehouse alongside Tom Hiddleston, and played Prince Arthur in Sir Trevor Nunn's production of Shakespeare's "King John".
Alongside his acting career, Bash is studying for A Levels in English, Philosophy and Film. He is a keen composer and, to date, has written music and lyrics for over 20 songs. He is currently working on orchestrating and professionally recording some of these.
Bash is proud to be an ambassador for "Fly High Billie", a school’s charity which promotes empathy, insight and compassion in young children, through its National B Kinder Day and Billie’s Workbooks, in memory of the beautiful Billie Kinder, who died in 2016 age 12. The charity honours her legacy of incredible kindness to others.
