Antoinette Beumer and five other crew members were badly injured in an accident on set, when a scaffold of over 9 feet high collapsed. She ended up with a broken arm and a broken jaw. For a few scenes Beumer was replaced by Erik Van Looy, the director of the original Loft - Tödliche Affären (2008) who was initially going to direct this remake as well. She made an amazingly quick recovery and resumed directorial duties after only a few weeks. Afterwards, she admitted that she could not see the differences between her scenes and the ones shot by van Looy.
