Two hour-long 1995 documentaries in the British Film Institute’s “Century of Cinema” series, about Scandinavian and Irish cinema. I Am Curious, Film, by Swedish film critic Stig Bjorkman, offers an intelligent if at times breezy survey that gives disproportionate weight to recent work and artists (like most of the documentaries in the series); Lars von Trier assumes the duty of explaining who Carl Dreyer was and, despite a couple of lovely clips, mainly flunks the assignment. It’s at it’s best when showing beautiful black-and-white clips from older films. I haven’t seen Ourselves Alone?, directed by Donald Taylor Black.
