LILONGWE, MALAWI — The southern African country of Malawi may not be what comes to mind when you think of kung fu movies. But four young acrobats in its capital, Lilongwe, are out to change that. The trailer for their first locally produced action flick, The Town Monger, has been generating buzz online and drawn interest from regional cable distributors. The film will premiere in Malawi this week.The buzz started soon after the director posted the film’s trailer online.“It is not what we expected, and we have been overwhelmed by the response," said Denis Imaan, manager of the Kufewa Acrobatics. "And we have taken some time now just to sit down, trying to strategize like ‘OK, where do we go from now?'”
