McCormack portrayed con artist Clark Rockefeller in the Lifetime television movie "Who Is Clark Rockefeller?", which premiered on March 13, 2010. To prepare for the role, he read everything on the case, including coverage of the case and Rockefeller's jailhouse interview. "Who Is Clark Rockefeller?" received mixed reaction, but McCormack's performance was favored by critics, with "Variety"'s Brian Lowry concluding, "...the real kitsch factor resides in Eric McCormack's performance as the suave charmer, which adds an element of high camp to the proceedings."
