I want to know the answer to the following question:
The play was the opening act for the starting of the 2013 season at which location?
All the background I'm provided with is that "The play also opened the 2013 season at Regent's Park Open Air Theatre in London where it played to full houses and starred Robert Sean Leonard as Atticus Finch, his first London appearance in 22 years.". Is that enough to answer the question?
Answer: yes
