Born in Nottingham and fiercely proud of his Welsh roots, Cian initially trained as an actor at RADA before moving behind the camera.
‍
His short ‘Duck Press’, starring Matthew Marsh and Jordan Scowen, is a love letter to gastronomy, the bond between fathers and sons, and our appetite for life when we need it most.
‍
The film had its world premiere at the 26th Newport Beach Film Festival in California, before screening at Berlin British Shorts, the 20th Poppy Jasper International Film Festival and the 22nd Dam Short Film Festival.
‍
His chess-infused romantic comedy ‘The Fool’s Mate’ premiered at Bolton International Film Festival, won Best Short Film at Cambria Film Festival, California, and has garnered over 220k views since its online release.
‍
He is currently in post-production on ‘The Vicar: A Holy Catastrophe’ — a comedy of biblical proportions with a touch of the lusty.
‍
Cian also conceived and directed ‘Music To Move You’, a narrative spec ad for Heart FM exploring how music can give us the courage to live outwardly what was once private. The film was selected for Berlin Commercial RAW ’24 and shortlisted at the 1.4 Awards ’25.
‍
In 2024, he crafted the music video for ‘Greek Street Friday’, the title track of world-renowned jazz artist Ian Shaw’s latest album.

In August 2024, having crowdfunded 14k, Cian shot his latest short, 'Duck Press', starring Matthew Marsh (Dunkirk, Tetris, The Mauritanian, The Crucial - N.T & West End) and Jordan Scowen (Maters of the Air, Oedipus - West End).
‍
Earlier that year he collaborated with world renowned UK jazz singer, Ian Shaw, directing the music video to the title track of his album, 'Greek Street Friday' - as featured on promonews.tv -  ‘Llewellyn crafts an evocative and affectionate showcase for artist and song.’

Always interested in the art of authentic advertising, in 2023 Cian conceived and directed, 'Music To Move You' - ‍a speculative Ad for Heart FM, shot on practically no budget, which featured in Berlin Commercial Raw Selection '24 and was shortlisted at the 1.4 Awards '25.

It gained critical praise from advertising executives - 'Spec Ads don’t get better than this.’ - Simon Elborne, MP and Exec Producer at Outsider
‍
His debut short, ‘The Outing’ gained UK and US recognition, picking up 11 Official Selections and 4 Awards including ‘Best Short Comedy’ at the Wales International Film Festival.

He  currently has a feature in development.

Cian’s work is heavily influenced by the principles and philosophies learnt whilst training at the Royal Academy of Dramatic Art and National Youth Theatre. Since then he has performed at the Royal Festival Hall, Royal Albert Hall and the Edinburgh Fringe; all of which have helped shape his style and understanding of nuance in performance.

He co-created the theatre company, ‘Cian and Al’ staging witty, physical comedies such as John Mortimer’s ‘The Dock Brief’ and Michael Frayn’s ‘Matchbox Theatre’ to great acclaim. Find reviews of both productions below along with stills in the gallery. 

When not directing, Cian previously worked within the AD (Assistant Director) department on commercials and high end TV dramas. He has worked alongside OSCAR and BAFTA winning directors such as Steve McQueen on the critically acclaimed ‘Small Axe,’ Jonathan Glazer on his short ‘The Fall’, and James Strong on ‘Liar’, produced by Two Brothers Pictures.

Working on productions of such scale has given Cian invaluable experience which he continues to take forward in his own work.

Commercially, he’s worked for brands such as Alexander McQueen, Burberry, The Princes Trust, 02, Virgin and BT, as well as artists: The Foals, M.I.A and Travis Scott. ‍
