Six Four is a 2023 British crime thriller television series set in Glasgow and Edinburgh starring Kevin McKidd, Vinette Robinson, Alex Ferns and James Cosmo. It is an adaptation of the 2012 novel by Hideo Yokoyama. It was made available on ITVX in the United Kingdom from 30 March 2023.
Chris (McKidd) and Michelle (Robinson) are parents to a missing child, but a wider conspiracy may link the father (Cosmo) of another missing child to Chris' brother, Philip (Whipp).
The series is produced by House Productions. Clare Kerr is producer and Ben A. Williams is director. Gregory Burke is script writer executive producer alongside Juliette Howell, Tessa Ross and Molly Bolt. Clare Mcquillan is also a writer on the series. Burke described the series as a âÂÂhuman story about two people under incredible amounts of pressure, who both choose to try and address their pasts. It is a story about how chance can define a lifetime, exploring the corruption that runs through institutions, and examining the secrets and monsters that lurk in every family.â The adaptation moves the setting from Kyoto in Japan to Glasgow, Scotland with the main characterâÂÂs name changing from Mikami to Chris. Script writer Gregory Burke explained the move by saying âÂÂIn recent years we have not lacked our own examples of institutional inertia. Our public life and collective health has been jeopardised by corruption. In many of these situations the same dilemma is at their core; to what is the individual within the institution loyal, and does that loyalty inevitably lead to a compromise with the truth.âÂÂ
Kevin McKidd and Vinette Robinson were revealed to be cast as Chris and Michelle Oâ Neill in May 2022.
Six Four was filmed in both Glasgow and Edinburgh in Scotland in the summer of 2022.
