Last Night I Saw You Smiling finds filmmaker Kavich Neang documenting the final days of the White Building. An architectural landmark in Phnom Penh built in the 1960s, the building was earmarked for destruction in 2017. Originally built as social housing for moderate income tenants, the White Building stood as witness to the history of the past 50 years in Cambodia. After the building (and city) became empty due to the Khmer Rouge’s brutal regime in the 1970s, tenants relocated to a building that came into increasing disrepair while simultaneously nurturing a community of artists, educators and neighbours. Neang films residents packing up their lives in the final week before moving out, conversing about their own personal histories and how they intertwine with the White Building and Cambodia at large.
