With an empty gallery to preside over, Clark contemplated volunteering for the Royal Naval Volunteer Reserve, but was recruited, at Lord Lee's instigation, into the newly-formed Ministry of Information, where he was put in charge of the film division, and was later promoted to be controller of home publicity. He set up the War Artists' Advisory Committee, and persuaded the government to employ official war artists in considerable numbers. There were up to two hundred engaged under Clark's initiative. Those designated "official war artists" included Edward Ardizzone, Paul and John Nash, Mervyn Peake, John Piper and Graham Sutherland. Artists employed on short-term contracts included Jacob Epstein, Laura Knight, L. S. Lowry, Henry Moore and Stanley Spencer.
