Secretariat

Incredible horse lifts a beleaguered nation's heart - pure Disneyana

Americans apparently revere their great racehorses, especially if they carry their weight in socio-political resonance - or its absence. Thus, the $58 million-grossing Secretariat, about the powerful red chestnut with the inordinately huge heart whose bid to win the 1973 US Triple Crown supposedly diverted attention from Watergate and Vietnam, arrived comparatively quickly after Seabiscuit, the 2003 Best Picture Oscar nominee and second film about the undersized knobbly-kneed bay who thrilled Americans during the Great Depression.

Eadweard Muybridge, Tate Britain

Trotting horses were only a small part of a fascinating story

Multiple images of silhouetted horses cantering against blank backgrounds in grids of movement are what most people associate with Eadward Muybridge. Made in the late 1880s, they have contributed to his lasting reputation as a pioneer of photography and the moving image. So it is astonishing to discover through Tate Britain’s magnificent exhibition of his life’s work, that horses were only part of a story packed with surprises.

Mountain Gorillas, BBC Two/ Horsepower with Martin Clunes, ITV1

Fabulous camerawork turned into Gorilla EastEnders

People are lured to behave like animals for TV now - Big Brother, Celebrity Jungle, The X Factor - so it merely completes the idiotic equation to have animals insistently transfigured into little humans in wildlife TV. Or big, hairy humans in the case of mountain gorillas and Martin Clunes.

Art Gallery: Fourth Plinth Commission

A playfully subversive mood dominates this strong shortlist

A playful, subversive mood dominates the shortlist for Trafalgar Square’s Fourth Plinth. Most of the six proposals, in what is a very strong shortlist, play on notions of British identity, probing themes of heroism, heritage and conquest. The models, which include a cock (the winged variety), a cake and a kid on a rocking horse, were unveiled yesterday by Mayor Boris Johnson. Two winners will be selected next spring, with the first appearing on the Plinth at the end of next year. The six are:

Interview: Liz Mermin on Horses

The director discusses her fascinating documentary about racing thoroughbreds

Whoever first made the observation - some say Winston Churchill, others Ronald Reagan - there is something about the outside of a horse that is good for the inside of a man, and a woman. On stage these noble beasts have inspired some highly successful plays, including Peter Schaffer's Equus, recently revived with Daniel Radcliffe, and War Horse, still living up to its name in the West End after over two years (panto horses probably don't count). In cinema, the legacy is more mixed; but not for nothing is the Western, arguably the greatest of film genres, also known as the horse opera. Horses, Liz Mermin's intensely strange documentary, is a fascinating addition to this stable.
