The Wine March

If there was ever a good excuse to drink wine, this is it. Raising money to build water projects in poverty-stricken areas of the developing world, the 2Water Wine March is a five mile walk along the Thames, with stops for wine tasting along the way. Led by the Three Wine Men – TV wine experts Oz Clark, Olly Smith and Tim Atkin MW – the march starts with a glass of wine at Vinopolis, before heading east via Gordon Ramsay’s The Narrow to Canary Wharf gastropub The Gun. Tickets are £15 and include a glass of wine at each stop, with all proceeds going to the 2Water charity. 3 Mar

Angela Williams – An Hour with Audrey Hepburn at the Heartbreak Gallery

Head to the aptly named Heartbreak Gallery to see stunning photographs of Audrey Hepburn, many of which are on display for the first time. Taken at the Ritz in 1964, the photographs capture the actress’s innate glamour, charisma and beauty, and are sure to have you longing for a bygone era. Follow this with a look at Williams’ snaps of other 60s icons, displayed in the adjoining room. Entry is free. 27 Feb – 31 Mar 

More events in London

This exquisite collection of over 70 portraits celebrates the golden Hollywood era and the Hollywood stars that captivated the world between the 1920s and the 1960s and beyond.  

They were part of the infamous star system that large film studios like MGM had in place and their images were strictly controlled by these studios. 

Image was of the upmost importance and the portraits convey the fascination and god-like appeal of these stars.  It is perhaps because of these images that they became such celebrated stars. 

There are  many included such as Clark Gable, Marlene Dietrich, James Dean and Audrey Hepburn to name just a few. The collection is immense and fabulous.

I especially loved the portraits of Ava Gardner, Grace Kelly and James Stewart, having never seen them before.  It’s amazing to think that there are still unseen images of these icons and the beautiful vintage prints will surprise many.

It is a truly incredible collection which shows the importance of the photographer in the making of these stars resulting in images which forever capture the elegance and glamour of its day.

Glamour of the Gods at the National Portrait Gallery, until 23 Oct 2011. Book tickets
