The Birmingham Rep’s Lindsay Posner directed touring production of Harvey arrived at the West End’s Theatre Royal Haymarket last month for a two month residency until 2 May 2015.

This hilarious Pulitzer Prize winning comedy by Mary Chase, immortalised in the 1950 classic film starring Jimmy Stewart, was first produced on Broadway in 1944. It’s a whimsical fantasy about a wealthy a man and his constant companion Harvey – an invisible six foot 3 inch rabbit.

The play debuted in London after the war and since then Stewart himself made his West End debut in the 1975 revival and Gordon (Allo, Allo!) Kaye featured twenty years later at the Shaftesubry Theatre.

Another twenty years on James Dreyfus takes on the lead role of Elwood P. Dowd and Maureen Lipman is Veta, his socially ambitious and enjoyably deranged sister. What The Telegraph’s Dominic Cavendish calls “screwball magic”.

Maureen’s extensive theatre and screen work includes an Olivier Award in 1985 for See How They Run, The Sweeney, Smiley’s People, Coronation Street, Jonathan Creek, Holby City, Educating Rita and The Pianist.

French born James Dreyfus had his first television break in the BBC comedy series Absolutely Fabulous and has created memorable comedy characters such as Constable Kevin Goody in Ben Elton’s sitcom The Thin Blue Line and Tom Farrell, the gay flatmate in Gimme Gimme Gimme. He won the Best Supporting Performance in a Musical Olivier Award for the Lady in the Dark at the National in 1998.

I caught up with Maureen and James at the stage door before an evening performance a couple of weeks ago and both thankfully liked the drawing. Maureen has signed a sketch for me before and we had a brief discussion about drawing styles and capturing a likeness.

She said her portrait painter said that she was difficult to capture. She did like this sketch. My response was that because she has a variety of expressions – obviously an actor’s bread and butter – sometimes catering an expression can contradict a likeness, so portraits aren’t always physically representational.

Maureen’s such a great comic actress, relying on expression (and timing) so in my opinion makes a perfect drawing subject using a ‘lively pencil’ with plenty of energy.
