Portuguese auteur Pedro Costa’s Colossal Youth (2006) is a shadowy study in exile, set in and starring a Lisbon neighbourhood of Cape Verdean migrant workers. Ventura is the damaged, dignified old man who fills nearly every scene. With a lurching walk and disturbed, sad stare, dictating letters to relatives who no longer exist and lending an ear to the local heroin-addict mum he calls his daughter, he’s alienated yet loving. “The ceiling is full of spiders,” he imaginatively complains to a letting agent, as he refuses yet another pristine impersonal flat in the new block the neighbourhood is being moved down the line to, displacement their permanent condition.
