A selection of theatre reviews:
King Lear and Taming of the Shrew for the ETT, directed by Stephen Unwin:
‘I liked Grant Gillespie’s Oswald, not an easy part to play, paradoxically, because the character can easily seem simply naff and smarmy. Gillespie plays him as smug and sly, an objectionable little man who thinks he knows how to make the best of other people’s disasters.’ John Peter, The Sunday Times.
‘Grant Gillespie’s self-seeking Oswald personifies the moral vacuum at the heart of the new regime.’ Fiona Mountford, Evening Standard.
‘There is some excellent work from Grant Gillespie as an unusually vivid Oswald.’ John Gross, The Sunday Telegraph.
‘In the small but significant role of Oswald, Grant Gillespie shows how a weak man becomes a monster.’ Lyn Gardner, The Guardian.
‘Grant Gillespie gives a very modern feeling to the eye rolling insolence of Oswald.’ BBCi
‘Oswald (Grant Gillespie) provides the only flicker of light relief in this dark and bleak drama.’ Robert Tanitch, Morning Star.
‘Grant Gillespie plays the intelligent courtier and confidential go-between with affectation and camp delight, his dying act of humanity changing the course of the play.’ Kevin Quarmby, Rogues and Vagabonds.
‘Grant Gillespie’s marvellously fey and effete Oswald is another little gem, rolling on and off the stage on what appears to be frictionless castors and bowing foppishly to just about anyone in his sights.’ Teletext.
‘Role playing pays off handsomely, not least with Grant Gillespie switching from Sly’s high-heeled wife to a Birkenhead Biondello.’ Michael Billington, The Guardian.
‘The real scene stealer is Grant Gillespie’s deliciously camp Liverpudlian Biondello.’ Terry Grimley. Birmingham Post.
‘In the role of Biondello Grant Gillespie’s natural charm and Scouse accent worked perfectly.’ Alan Kersey, Cambridge Evening News.
‘The supporting cast weigh in with some excellent performances, particularly Grant Gillespie’s lovelorn peasant Peter.’ Jane Tadman. Sheffield Telegraph.
‘A splendidly scene-stealing turn from Grant Gillespie as the bewildered beau.’ John Highfield, The Star.
‘Lucy Briers and Grant Gillespie inject some delightful broad comedy.’ Lynda Murdin, Yorkshire Post.
‘There is some truly outstanding supporting cast in Lucy Briers and Grant Gillespie a delightful comic double act as rustic young lovers.’ John Highfield, The Stage.
‘Grant Gillespie musters real conviction.’ Nicholas De Jongh, Evening Standard.
‘Grant Gillespie is impressive as a choric beggar who, clad in striped blazer and white flannels, looks as if he opens the batting for the Corinthian Casuals.’ Michael Billington, Guardian.
‘Grant Gillespie’s dissolute Sebastian Flyte of a choric beggar captures a wily sardonic detachment.’ Ian Johns, The Times.
‘Sardonic and cool, Grant Gillespie as the Beggar, dispenses witty and accurate colloquialisms.’ Glen Baker, Morning Star.
‘Grant Gillespie likeably amalgamates the comic and earnest phases of Kit Nubbles.’ Benedict Nightingale, The Times.
School for Scandal for Theatre Royal Bath, directed by Jamie Lloyd:
‘The verbal confusion continues with additional tales from fellow gossipmongers, including the flamboyantly outrageous Sir Benjamin Backbite, perfectly portrayed by Grant Gillespie.’ Rob Holcroft, Worcester Standard.
