If you were walking through the Chesham Building on the afternoon of Tuesday 15 July and happened to spy numerous bulky men dressed as U.S. Secret Service agents running up and down the outside staircases with their earpieces embedded and guns drawn, you were not dreaming. Luckily, they were just actors filming a scene from “The Curse of Hendon,” a forthcoming feature which has been filming around the Chesham Building in recent days, especially in the alley below CMCI staff members’ offices on the west side of the building. According to internet reports, the film stars Sasha Baron Cohen, but he was not sighted by your intrepid reporter. Too bad, since he’s actually one celeb this correspondent wouldn’t mind having a chat with.
