If you were in Harpenden's sainsburys tonight you may have spotted Rupert Grint, of Harry Potter fame, he was in there at about six! Who says nothing ever happens in Harpenden?!?!
We do get other famous visitors! The late Stanley Kubrick used to live at Childwickbury. During the filming of (Eyes Wide Shut,~1999) Tom Cruise and Nicole Kidman dined in the then Café Blue Dog (now Café Gusto). The Blue Dog was more a restaurant. Whether the man himself did I do not know.
