Technology is a fascinating feature of old movies to me. Like when you see someone typing away on their
typewriter, producing their epic novel (while screwing up & throwing away sheet after typed sheet, because they can't get the words quite right.)
..... Or telephones. The heroine will survive, but if only she can get to the nearest phone & make that call & alert the police! But will she have the right coins to make the call, once she's located a phone box? Or perhaps the phone cord will be cut just at the critical moment & communication won't be possible? It would be so easy if she just had a cell phone!
This little clip is from an old Alfred Hitchcock film,
Dial M for Murder, in which the phone features very prominently. In fact, it's almost "the star" of the movie! :
