The four-part series was aired from 28 April till 19 May 2015 on BBC 1. He is best known the TV show "The Big Impression", formerly "Alistair McGowan's Big Impression". His celebrity impressions include David Beckham, Sven-Göran Eriksson, Gary Lineker, Nicky Campbell, Richard Madeley, Tony Blair, Prince Charles, Robert Kilroy-Silk, Laurence Llewelyn-Bowen, Angus Deayton, Terry Wogan and the fictional characters Ross Geller (from "Friends") and Dot Cotton (from "EastEnders"). McGowan and Ronni Ancona are probably best known for their portrayal of Posh and Becks with McGowan exaggerating David Beckham's perceived lack of intelligence and Ancona exaggerating the role of "Posh Spice" (Victoria Beckham) with pouting lips. As the Beckhams' style of dress regularly changed – in particular David's changing haircuts – McGowan adapted his costumes and style accordingly. In later years he developed his portrayal of Beckham into a brainiac infuriated by Posh's lack of intelligence. He made a return to dramatic acting in 2005, appearing in the BBC's adaptation of Charles Dickens's novel "Bleak House". He also appeared at the Chichester Festival Theatre in two plays; the first was a new translation of Nikolai Gogol's The Government Inspector by Alistair Beaton, the second was a new play called 5/11, which was produced to mark the 400 year anniversary of the Gunpowder Plot. In 2006 he starred in the detective series "Mayo". He also presented an episode of "Have I Got News for You" on 20 October 2006. He joined the Royal Shakespeare Company for the Christmas 2006 season playing Mr Page in "Merry Wives: the Musical" (a version of "The Merry Wives of Windsor") opposite Judi Dench, Simon Callow and Haydn Gwynne. Despite his acting commitments, he continued to appear on BBC Radio and television as an announcer and as an impersonator. He has re-voiced video footage of "BBC Sports Personality of the Year" and "Match of the Day". In 2007 McGowan starred as Orin Scrivello (and other, smaller characters) in the West End transfer of the Menier Chocolate Factory's revival of "Little Shop of Horrors", and filmed "My Life in Ruins", an American comedy film set in the ruins of ancient Greece. In 2008 he made his directing debut at Guildhall School of Music and Drama with Noël Coward's classic comedy Semi-Monde.
