I want to know the answer to the following question:
2013's The Last Stand marked Schwarzenegger's first starring role in how long?
All the background I'm provided with is that "He appeared in The Expendables 2 (2012), and starred in The Last Stand (2013), his first leading role in 10 years, and Escape Plan (2013), his first co-starring role alongside Sylvester Stallone.". Is that enough to answer the question?
