About a week ago, watched "Kiss Me Deadly", a 1955 B&W Mike Hammer crime drama. Hammer lives in a Mid-Century modern apartment on L.A.`s Wilshire Blvd., complete with a reel-to-reel controlled answering machine which appears to run at around 30 ips !
Also, in "True Lies", there was an R2R among the gear in their surveillance van.
And, in the French cult film "Diva", the much sought-after bootleg opera tape was made clandestinely by the young postman, using his very cool Nagra portable R2R, concealed in his mail bag.
