Financial Times critic in May 2006: "I have seen actors from Alan Bates to Matthew Macfadyen play Shakespeare’s Benedick, but Joseph Millson’s performance in the new RSC production strikes me as definitive. Handsome in voice and in person, he can carry the audience on his roar and draw it into his hush. The elements of wit, anger and vulnerability are thrillingly mixed in this actor".
Millson married singer and Actress Caroline Fitzgerald in the summer of 1999. The two had two children, Jessica and Gabriel. In mid-2012, he dated Downton Abbey Actress Michelle Dockery for five months. In October 2012, it was reported in various media outlets that they had split. Millson met his current wife Sarah-Jane Potts in 2011 while they were co-workers on Holby City, the medical drama television series. The two wed on 31 December 2013. Millson has a stepson, Buster, from Potts' first's marriage to actor Tony Denman.
