Whatsisname button

Have you ever tried to watch a film on television while a talkative friend or relative constantly asks questions? "Oooh, isn't that Whatsisname? What was that other thing he was in? You know, the one with her out of Whatchamacallit?"

I propose an extra button for the TV remote control, which when pressed would pause the picture, and link to a database such as imdb.com. Broadcasters could transmit data alongside the picture like they do with teletext, containing ID information for the actors currently on screen. Using the arrow controls on your remote, highlight the link for the actor in question and click to bring up their name and history of their entire career.

This should be bakeable with existing technology - but it might take some time to watch a film with forgetful elderly relatives.
