Approximately 1h15m40s into the film, right after Elvis mentions a $5000 contribution to the DoJ Narcotics department, the shot changes to that of the blue carpet in the room where Nixon is briefed by Bob Haldeman. The seal on the carpet mistakenly reads "PLUAIBUS" in the "E PLURIBUS UNUM".
Set in 1970, Elvis is seen in his hotel room watching "Big Jake" on television. "Big Jake" wasn't produced until 1971 and didn't premiere on television until 1976.
