'Brangelina', couple like no other

Jolie files for divorce from Pitt, citing irreconcilable differences and seeking custody of their six children

The end of Brad Pitt and Angelina Jolie's marriage provoked a worldwide media storm on Tuesday because this "socially engaged" couple had given the impression that theirs was a partnership which worked both publicly and privately, according to a leading celebrity magazine editor.

Like legendary Hollywood couples before them including Elizabeth Taylor and Richard Burton, and Lauren Bacall and Humphrey Bogart, love blossomed on set, the actors falling for each other in 2004 while filming Mr and Mrs Smith - a movie about marriage.
