They've been operating successfully out of Gramps for several months, but the local improv and sketch-comedy folks of Villain Theater have needed their own space since leaving their former digs at MADE at the Citadel. Their new home around the corner from the Little Haiti Cultural Center is finally ready, and the Villain Theater Grand Opening is sure to be a party of unexpected proportions. Billy Corben will be a special guest within a night of performances, Gramps will provide drinks and food, and the afterparty will offer karaoke, drag performances, and other diversions. 7:30 p.m. Saturday at Villain Theater, 5865 NE Second Ave., Miami; villaintheater.com. Admission costs $12.
