Nimax Theatres, which owns the Apollo along with several other London theatres, had initially canceled performances through Jan. 4 while the theatre undergoes construction and safety evaluations.
The Dec. 19 partial roof collapse, which injured over 80 people, occurred just after 8:15 PM GMT, following a major thunderstorm that drenched London with 15 percent of an average December's rainfall within an hour.
An expert told the Express that he believed rainwater seeped into the building, increasing stress on the ceiling. "This puts pressure on it – and it crumbles and collapses."
Legal experts told the Evening Standard that damages claims for the Dec. 19 performance could exceed £1 million. "If there was to be some sort of class action, it is something I would look at. This is the problem with going to public events held in century-old buildings — but you still don’t expect to be in any danger," said Dec. 19 audience member Martin Bostock, who was injured in the ceiling collapse.
