The third collaboration between Colin Firth and Nicole Kidman, and this is first time they don't portray each other's spouse. They previously starred in The Railway Man (2013) and Before I Go to Sleep (2014). This also marks the second collaboration between Kidman and Jude Law, after Cold Mountain (2003).
Roadside Attractions will premiere the film at Berlin Film Festival and release the film theatrically in July. The distribution company used the exact same release strategy for Mr. Holmes (2015), also starring Laura Linney, that went on to become a summer sleeper hit among mature audiences.
