Directed by a black writer, musician and director born in Ghana in 1957 and influential on the British arts scene for the past quarter of a century, this many-layered poetic documentary combines a variety of journeys. The central, mythic ones come from Homer's Odyssey: Ulysses's homecoming and Telemachus's search for his father. Mingled with these are the postwar exoduses from the Caribbean beginning with the Windrush, and from India mostly by plane, with Britain as their destination, which are evoked by archive material from newsreels and old documentaries, underpinned by some striking, austerely beautiful footage shot in wintry Alaska while Akomfrah was working on a documentary. Readings on the soundtrack and brief quotations printed on the screen tell of journeys taken, contemplated and imagined by a couple of dozen writers, ranging in time from the Song of Solomon via Dante and Shakespeare to Beckett and Joyce. A handsome, restful, thought-provoking film.
