Please note that some helmets or masks made by latex or PVC materials are completed with the standard size costume at the same time (they made based on adult size), so it may be too large for children. While some theater chains are prohibiting certain items like props or masks, Landmark’s ban is the most restrictive for Joker cosplay fans. Popular challenges, including the geeks’ makeovers, will return, as well as gladiator-style battles and a cosplay event.
