When Elizabeth imagines Tony Blair's coronation, the royal cypher on his chair reads "TIR" (or Tony Rex I). A royal cypher, as Elizabeth would surely know, would never include a Roman numeral I because British monarchs don't receive an ordinal until a second monarch takes the same name, so his cypher should only read "TR" (similar to the last unnumbered monarch Queen Victoria, whose cypher was VR).
A wide-screen high-def (HDTV) camera is shown taping Tony Blair's Chicago speech at 16:35. While limited HDTV broadcasts had begun in the US just a few months before, Blair's speech was actually recorded in the older 4:3 format.
