Strike

Strike is a 1925 Soviet silent propaganda film directed and edited by Sergei Eisenstein. Originating as one entry out of a proposed seven-part series titled "Towards Dictatorship of the Proletariat", Strike was a joint collaboration between the Proletcult Theatre and the film studio Goskino. As Eisenstein's first full-length feature film, it marked his transition from theatre to cinema, and his next film Battleship Potemkin emerged from the same film cycle.
