Who directed the Oscar-nominated drama "The Insider" from 1999 starring Russell Crowe?

Explanation

Russel Crowe is Australian, but was born in New Zealand. He has had major blockbusters throughout his career, but his cooperation with Ridley Scott has been particularly fruitful. His breakthrough came with the violent action movie "Romper Stomper", though he first attracted major attention for his part in Michael Mann's "The Insider". Just one year later, he was awarded an Oscar for his performance in Ridley Scott's "Gladiator". Ron Howard's "A Beautiful Mind" from 2001 was also a major hit. Lately, Crowe has continued his cooperation with Ridley Scott with movies such as "American Gangster", "Body of Lies" and "Robin Hood".
