A heritage Brisbane building looks set to double for an American university campus in Dwayne "The Rock" Johnson's Young Rock. Filming for the NBC series about the formative years of the world's highest-paid actor was under way yesterday outside the Queensland Art Gallery, which has been a jewel in South Bank's crown since 1982. A large group of extras in retro clothes passed as students at the University of Miami, which Johnson attended in the late 1980s and early 1990s.
