The Fast Speaking Inmate was incarcerated at the Nazca sanatorium of Anthony de Padua in Peru, 1957. The man muttered in a furious blur of words as Mutt Williams and Indiana Jones passed by, as they were being shown to Harold Oxley's former cell.
Behind the scenes[]
The role of the Fast Speaking Inmate was played by Carlos Linares.
In the novelization, Williams translates one of the man's babbles as "archaeologist" and approaches him, only to be grabbed by the man. Jones managed to pull Williams back, and the two continue onto Oxley's cell.
