The Hollywood actor Ryan Reynolds and Burberry model Rosie Huntington-Whiteley front Marks & Spencer's autumn 2011 campaign by Rainey Kelly Campbell Roalfe/Y&R, shot by the photographer Greg Williams.
Meanwhile, the model David Gandy has been unveiled as the face of M&S's Collezione sub-brand.
The models and actresses Sophie Byron, Suki Waterhouse and Louise de Chevigny also appear in new in-store, online and print ads, shot by Rankin, for the store's Limited Collection.
The M&S executive director of marketing, Steve Sharp, said: "It’s a very different campaign for M&S as it’s the first time we have focused on one of our brands in this way. We are very proud of the result."
