I'll likely effectively not remember 'Oka!' in a few days. It's not necessarily 'bad' - 'forgettable' is more apt. Kris Marshall feels like quite odd casting, but he does the job no doubt. Will Yun Lee, Isaach de Bankolé and Mapumba do their bit too, but to be honest I wouldn't say it's a film that has noteworthing acting/actors....
