Miller and Murphy sign up for Hippie Hippie Shake
Based on a memoir, the movie uses the backdrop of a magazine lawsuit to take the characters on a journey through the swinging decade.
Hippie Hippie Shake is set to be directed by Beeban Kidron, whose most recent work was on Bridget Jones: The Edge of Reason, based on the second fictional diary of the eternal singleton.
Meanwhile, Miller and Murphy will also co-star in forthcoming film The Best Time of Our Lives - which Lindsay Lohan was cast in until recently - in addition to Keira Knightley, whose mum wrote the script.
Sienna can soon be seen on DVD in Factory Girl, while Cillian Murphy currently stars in Sunshine, a science fiction thriller showing in cinemas.
