EXPIRED Mack and Mabel: Save £5 on top price tickets at the Southwark Playhouse

Hollywood in the 1920s, a time when movies were silent and cinema was magic. Mack Sennett, 'King of Comedy' and creator of The Keystone Kops, discovers Mabel Normand, a waitress from Brooklyn, casts her in his two-reelers and turns her into a star. So began one of Hollywood's most tempestuous and heart-wrenching love stories. But life isn't like the movies - ambition, dalliance and the impending but inevitable threat of change put unbearable pressure on their relationship. Romance turns to jealousy as stardom invites scandal and heartbreak. Mack and Mabel at the Southwark Playhouse includes numbers such as Look What Happened To Mabel, I Won't Send Roses and Time Heals Everything.
