Megunica is a documentary film that follows street artist Blu & three friends on a journey through Latin America. The title is taken from the first letters of each country they visited — (Me)xico, (Gu)am, (Ni)caragua, (C)osta Rica & (A)rgentina. If the goal of a trailer is to capture the film’s guts and draw us in, I think this one hits it out of the park.
