Speaking with Simon Evans on Zoom, it is difficult not to wonder when Michael Sheen, David Tennant or (wouldn't it be glorious?) Judi Dench is going to drop in and yell at you. Never mind that Evans has never met Sheen ("Frost/Nixon," "The Queen") or Tennant ("Doctor Who," "Broadchurch"), at least not in real life. (He has met Dench, which obviously counts double.) For more than a year, "real life" has been a memory; life has been conducted to a large extent over Zoom and as co-creator, writer and co-star of "Staged," a BBC One comedy shot entirely on laptops and other personal devices, Evans is a maestro of Zoom. Meeting him there is a bit like walking down the main street of a small Maine town with Stephen King â it seems very normal and familiar except for the nagging feeling that anything, or anyone, could pop out at any time.
