Join a theater full of Christopher Guest fans for the final two flicks in Charleston Music Hall’s film series. The screenwriter, composer, musician, director, actor, and comedian is known for his “mockumentaries” in which dialogue is often improvised, and this month’s films are no exception. On April 4, catch Best in Show, about five owners and handlers who enter their pooches in a prestigious dog show. Many of the same actors appear in April 16’s A Mighty Wind, in which three folk bands reunite for the first time in decades to perform in a TV concert. Charleston Music Hall, 37 John St. Wednesday & Monday, 7:30 p.m. $8. (843) 853-2252, www.charlestonmusichall.com
