In November 2012, McCallum began creating a body of portraits depicting defendants standing trial before international courts titled Weights and Measures. He began this project in partnership with the Coalition for the International Criminal Court as the organization's year-long artist-in-residence. The project consists of oil paintings portraying individuals standing trial before the International Criminal Court, as well as the ad hoc international tribunals that preceded it, such as the Special Court for Sierra Leone, the Extraordinary Chambers in the Courts of Cambodia, the International Criminal Tribunal for Rwanda, and the International Criminal Tribunal for the former Yugoslavia. According to an interview with MSNBC, the paintings are monumental formal portraits, referring to a classical, 19th-century approach to portraiture. They challenge viewers to reconsider the harmful influence the powerful male subjects of these portraits had on their communities.Fielding, Alex.
