Rachel Dodes looks at the rise of texting onscreen in movies/television. In House of Cards:
Executive producer David Fincher, who directed the first two episodes of the show, decided that he wanted the texts to appear almost as text bubbles with a pale blue or gray background, depending on who was sending the message, as opposed to showing close-ups of phones. After he proposed the caption idea, Mr. Willimon showed him some clips from “Sherlock,” which depicts texts on screen as white subtitles in a Helvetica font, and asked “Is this what you had in mind?” Mr. Fincher “was a bit bummed that it had been done before,” he says. “But good ideas are good ideas.”
Indeed. I really liked the way texting was handled in House of Cards, right down to the iOS-like details.
