I want to know the answer to the following question:
On what date in 2011 was the hold on Schwarzenegger's movie projects announced?
All the background I'm provided with is that "On May 20, 2011, Schwarzenegger's entertainment counsel announced that all movie projects currently in development were being halted: "Schwarzenegger is focusing on personal matters and is not willing to commit to any production schedules or timelines".". Is that enough to answer the question?
