Hong Kong Film Festival UK returns for its third edition from 12–28 September in London, presenting reflective, boundary-shifting cinema from Hong Kong and the ESEA diaspora. This year’s programme foregrounds transient and transitioning identities, exploring perspectives on migration, activism, marginalised communities, and gender, highlighting also the creative lens of women filmmakers. From dynamic contemporary works to intimate personal narratives, the festival centres voices that challenge, navigate, and reimagine belonging. Supported by the BFI. A box office sensation and the talk of the town, Four Trails (香港四徑大步走) brilliantly captures Hong Kong’s breathtaking natural beauty which are often eclipsed by its towering skyline. Among this, a different Hong Kong emerges. 72 hours, 298km, more than 4,800m of vertical elevation change - this is Hong Kong’s most daunting athletic challenge, where ultra runners strive to cover the city’s four iconic hiking trails in one go. The success rate is only 6%, yet each year, 15-25 runners take on this task to test their ultimate endurance. No trekking poles, no music, and no sleep. Just pushing physical boundaries to their limit. An up close documentary, Four Trails is Robin Lee’s impressive debut feature length film, winning him Best New Director at the Hong Kong Film Awards. Accounting for the challenge’s 2021 edition, the film explores its origins and the athletes that dare. Some held ambitions to break the impossible 50 hour barrier, others grew delirious as they trekked through darkness. The concrete jungle blends into wilderness, and bodies persist against mountains and seas. Followed by in-person Q&A with Jacky Leung, the first person to “break 50” featured in the film.
