Olivia Colman celebration at this year’s 30th Chichester International Film Festival

Without it, the whole festival risks being rather too male-dominated, says artistic director Roger Gibson.

But above all, the retrospective will celebrate a remarkable talent with a remarkable catalogue of films behind her.

Roger said: “She is obviously an actor who is coming to her peak and I think her range is extraordinary.

" People don't walk out of a Judi Dench and Maggie Smith film but they do with an Olivia Colman film sometimes because she is an actor who is always very brave in the choices that she makes.

" Some of her films are really quite challenging.”

The retrospective includes:
