This will keep any true 24 fan quiet until season 6 starts.
It isn't just a collection of photos - Jon Cassar who took a lot of the photos himself and is Director/Co Executive Producer of 24, provides an insight into what was happening at the time the photos were taken, such as the one taken on the 24 set when the crew were gathering around watching the news unfold on the morning on 11 September 2001, during the filming of season 1 of 24, before any episodes had aired.
Some of the best photos are the ones where people are caught relaxing or having a laugh with each other, it takes you a little way towards knowing what it must be like to work on a show like 24.
There is a behind the scenes DVD included as well (region 1) - which has interviews with Jon Cassar and others who took some of the photos in the book. The DVD isn't very long at only 7 minutes though!
A quality book, well worth ten quid.
