Documentary has been the artform for the twenty-first century. Digital technologies have made professional movie-making tools accessible to anyone with a computer, and digital television and web broadcast has brought a wealth of viewing opportunities to international audiences. From Supersize Me to An Incovenient Truth to Bombay Beach, the stories that a man with a movie camera has access to are the most riveting form of news and contemporary cultural information. An offset of this has been that conventional feature film documentary has had a renewed eminence, and truly great examples, films like Asif Kapadia's Senna, find a general audience that might otherwise not take an interest in.

Kevin Macdonald was one of the great contemporary documentary makers. With films including Touching the Void and the Oscar-winning One Day in September, Macdonald was revisioning how to tell a non-fiction story for cinema, television and home video. Success being what it is, Macdonald went to Hollywood and made critically and commercially lauded movies including State of Play and The Last King of Scotland. He returns to his popular roots with his latest film, the feature documentary, Marley.

You know the man, though mightn't know the complete story. Bob Marley was a true visionary, and one of the twentieth century's greatest musicians. From incredibly humble beginnings, Marley transformed the popular sound of reggae until it was both true to its urban roots and an evocation of a Caribbean sensibility that is as romantic as a summer holiday. This detailed look at the man's life takes in as much as the frame of the cinema screen can hold, and reveals that there is much about Marley that is relatively unknown. A really fantastic film (please mind the value judgement), Macdonald manages to hold a balance between demystifying his subject while still maintaining a reverence for the legend. (Here is where I'll qualify my previous value judgement): The mark of a good film, better yet a documentary, is one that will thrall fans and non-fans alike. The subject might be legendary to some, but the film is simply gripping for anyone who enjoys a good movie.

Marley is on general release.

5x15 is a literary initiative. If that sounds boring, it's only due to your dear Culture Editor's pervasive inadequacy with the written word. We hope to have instilled in enough trust in you that you, once, perhaps twice, would allow us to show you something a little less than mainstream.

But you wouldn't want the kind of event that 5x15 is to become too mainstream. Instigated by Rosie Boycott, Daisy Leitch and Eleanor O'Keeffe, the night brings together five literary minds and allows them the space to speak for fifteen minutes apiece, unfettered. Its reputation is such that all manner of cultural personalities are lining up to speak. They've had so far names including Nick Broomfield, Geoff Dyer, Mike Figgis, Craig Brown, Eve Ensler, Alan De Botton and Howard Jacobson, to come you'll have Salman Rushdie, Ben Okri, Simon Jenkins and William Dalrymple. Phew.

Tonight, at Gray's Inn, they have lined up Terry Waite, Crispin Blunt, Chris Moore, Nikita Lalwani and Noel 'Razor' Smith. More than one of these people has been imprisoned (it's not particularly relevant, but it's an interesting fact). Such a broad range of interest and experience, it's an event that keeps on giving.

5x15 is at Gray's Inn, tonight at 1900.

…and here, ladies and gentlemen, we have an example of The Saatchi Gallery doing what they do best: large group shows that survey a contemporary terrain in the visual arts. This time it's photography, and it's actually not bad.

There are a number of things that can go wrong with a large-scale group show, and mostly the pitfalls are around the difficulty of maintaining interest, the expected drop in quality of some works in relation to others, and the pomposity of trying to say too much about a subject. The Saatchi Gallery have been relatively consistent at this kind of work since they moved into their Kings Road digs, and of course while some shows felt better than others, this exhibition leaves a visitor with the impression that they've settled somewhat. This presentation, which will run throughout the summer, has some tough competition around town, the gallery clearly have a strategy in mind: popular medium, trendy names. It's the casual connoisseurs' summer show of choice.

Out of Focus is the show in question. It's The Saatchi Gallery's first major photography exhibition since I Am A Camera in 2001 and features the work of thirty-seven international artists. The gallery present a wide stretch of artists, from John Stezaker to the twenty-two year old Mohau Modisakeng, with both established and soon-to-be photographers in between. It's quite a list: Laurel Nakadate, Ryan McGinley, Broomberg & Chanarin, Katy Grannan, Mat Collishaw, Matthew Day Jackson…The extended list is quite an obvious choice of artists born between approximately 1965 - 1980; that's no bad thing per se, particularly when you've got Because favourites including A.L. Steiner and Michele Abeles, for example.

A polite tip of the hat to The Saatchi Gallery then for a job well done, and to consistency. Now, let's not let them sit on their laurels. You wouldn't want them to get boring, would you?

Out of Focus is at The Saatchi Gallery until 22 July.
