Siri Bunford is a Welsh-born director working with Knucklehead in the US and UK, with over 15 years directing commercials that combine cinematic beauty with character-driven storytelling. After a decade at Channel 4—where she rose to creative director of More4 making award-winning promos—she transitioned to commercials with work spanning global brands including Nike, Google, Guinness, HSBC, Sainsbury's, British Heart Foundation, and IKEA. Her signature approach blends mixed-media formats (film, Bolex 16mm, Alexa, iPhone) within single campaigns and emphasizes meticulous production design and casting. Notable projects include the Kubrick Season promo (a single 60-second Steadicam shot executed in 21 takes), Sainsbury's Food Dancing choreography, and the VISA campaign featuring refugee swimmer Yusra Mardini. Bunford has executed complex global productions—including a six-week Nike shoot in China and helicopter wildebeest filming in Tanzania for British Airways—while maintaining what she describes as making "things beautiful and real." Named Ad Age Directors to Watch 2008 and a D&AD Pencil winner, she focuses on finding humanity and contradictions in characters rather than specializing in single categories.
