Tom Cullen Bio

Thomas Cullen (born 17 July 1985) is a Welsh actor, writer and director who has worked across film, television and theatre. Born in Aberystwyth, Wales, Cullen trained at the Royal Welsh College of Music and Drama and emerged in the early 2010s as a distinctive screen presence following his leading performance in the film Weekend.

Early Life and Background

Thomas Cullen was born in Aberystwyth and is the son of two writers; his father is Irish and his mother is English. He spent his early childhood in Llandrindod Wells and moved to Cardiff at age 12, where he attended Llanishen High School.

Before committing to acting Cullen was involved in music, an early interest that accompanied his creative development. He trained formally at the Royal Welsh College of Music and Drama, graduating in 2009 with First Class Honours in Acting after spending a year at the Central School of Speech and Drama.

Path to Celebrity

While still in training Cullen was cast out of the Royal Welsh College to appear in short films that went on to win BAFTA Cymru awards, including Daddy’s Girl and Watch Me, work that introduced him to the Welsh film and television community. On stage he performed at venues such as the Bristol Old Vic and with National Theatre Wales, building a foundation in theatre that informed his screen work.

During this period Cullen co‑founded the Welsh company Undeb Theatre with Alexander Vlahos and wrote and produced short plays and a full‑length play titled Kingfisher. That combination of writing, producing and acting established his creative profile and led to wider casting opportunities on television and in independent film.
