Fernando Leon’s incisive, gripping film charts the rise and rise of Spanish left-wing party Podemos (We Can). Podemos was founded only a few years ago but has achieved astonishing success in wrenching power from the two major parties in the wake of crushing austerity that has caused widespread disillusionment. Leon shot hundreds of hours of footage; the resulting film is a fascinating look into the machinations of a grassroots movement. As the title cheekily suggests, the film also functions as a how-to for building leftist campaigns that can change the political landscape.
