Arts news and reviews with Mark Lawson. Ben Stiller reprises his role as a night security guard in Night at the Museum 2, the sequel to his 2006 hit. This time the action takes place at the Smithsonian Institution in Washington DC, where he enlists the help of the aviator Amelia Earhart, played by Amy Adams. Critic Mark Eccleston reviews the film. The Summer Exhibition at the Royal Academy in London is the largest open submission contemporary art exhibition in the world, drawing together a wide range of new works by both established and unknown living artists. Now in its 241st year, the exhibition includes around 1200 works, the majority of which are for sale. The theme this year is Making Space. Curators Richard Wilson and Eileen Cooper discuss their selections. Zinnie Harris is part of the successful writing team behind the BBC TV spy drama Spooks, as well as being an acclaimed playwright. Earlier this year she turned her hand to opera and now she has created a new version of Ibsen's A Doll's House at the Donmar Warehouse. Mark talks to Zinnie about some of the surprising parallels between the political backdrop of the play and today's political arena.
