Alistair McGowan's going Dotty again as he returns for a new series of uncannily realistic impersonations

Alistair McGowan's Big Impression 8.30pm BBC1
There will be many times during this first episode of the new series that you will be open-mouthed in admiration for the thoroughly eerie impressions by McGowan and his equally staggeringly talented sidekick Ronni Ancona.
Indeed, you might be so lost in examining just how McGowan can do such a good impersonation of EastEnders' Dot Cotton as Albert Steptoe, or Ancona as Christine Hamilton (she is terrifyingly good), that you'll miss the actual jokes.
But, no matter, as the jokes aren't really the point. It's the brilliance of the impressions, which are nuance-perfect. Ancona's Helen Baxendale has all of the right inflections, and McGowan's Richard Madeley possesses every last ounce of his subject's overbearing and patronising manner.
It's great fun - soap fans will doubtless laugh in recognition at McGowan's belligerent arm-crossing as the flighty Lynne Hobbs (nee Slater), and her refusal to serve anything but "two teas" to anyone who wants service in the EastEnders' caff.
And fans of Friends will readily identify with Ross's (McGowan) puzzlement at just what stage his life is supposed to be amid the confusion of repeats at various times on Channel 4, and the various series stages on Sky1 and E4.
