In 2011, Menzies featured as Dr. Joseph Cardin, opposite Keira Knightley's Karen Wright, in Lillian Hellman's 1934 drama "The Children's Hour", which focuses on the harmful effects of wrongful accusations and rumors. He would go on that same year to star in director Rupert Goold's "Decade", a play presented through a series of short vignettes penned to mark the tenth anniversary of the September 11th attacks on the World Trade Center in New York City. George Farquhar's 1706 play "The Recruiting Officer", which was based upon the methods used by the British Army to recruit troops during the War of Spanish Succession, saw Menzies star as Captain Plume during the first quarter of 2012. The next year, he would feature in director Carey Cracknell's "Rough Cuts: Searched", at the Royal Court Theatre, and star in National Theatre's experimental play "The Hush", which explored the connection between sound and memory.
