They were four brothers who couldn't have been more different and who ran what was perhaps the most fascinating of all the big Hollywood studios. Michael Freedland tells the story of the Warners who introduced the world to the pioneering talkie The Jazz Singer in 1927, the gangster films of the 30s, the war dramas of the 40s and the lavish productions of the 50s and 60s. With clips and music from the films, and interviews with stars like James Cagney and Loretta Young and a host of producers and directors.
