Baynton is one of the performers of the children's television series Horrible Histories, appearing in the first five series as an actor, singer, and occasional writer.[6]
Baynton and the other five members of the main Horrible Histories cast form the Them There troupe, which has since created other shows.
Along with the other members of the troupe, Baynton is the creator, writer, and star of Yonderland, a family fantasy comedy series that premiered on Sky One on 10 November 2013.[7] He starred with the same troupe in Bill, a BBCfamily comedy film based loosely around the early life of William Shakespeare, who ventures to London to pursue his dream of becoming a playwright.[8][9] The troupe also reunited in 2019 to create the BBC seriesGhosts, with Baynton appearing as a Romantic poet named Thomas Thorne.
Baynton teamed with friend and fellow Gavin & Stacey alumnus James Corden to create, write, and star in The Wrong Mans, a comedy thriller for BBC Two that premiered in autumn 2013.[10] The series is co-produced by online television provider Hulu.com in the United States, where it premiered in November 2013.[11] The first six-part series proved a critical and commercial success, and a similarly well-received two-part sequel was broadcast in December 2014.[12]
Baynton appeared at the 2013 Edinburgh Fringe Festival, starring in the world premiere of Tom Basden's play Holes.[14] He reprised his role of Gus in a London revival of the same play in summer 2014.[15]
Baynton is a former member of the band Special Benny as a vocalist and guitarist.[20] Their debut album Toys was released in 2010.
He has also performed as a solo act under the name Dog Ears. His debut solo EP, So It Goes, was released in November 2011.[21] It consists of four self-penned songs.
Baynton has commented on his son's skewed view of his father's profession: "He thinks work is putting on a beard. One day his eyes will be opened, but I do find it wonderful that that's his view of work."[23] He commented during the same interview that while many actors do not want their children to become actors as well, he sees no problem with his son following in his footsteps, stating that "if he enjoys it, so why shouldn't I let him?"[23] His son appeared as the young Mary, Queen of Scots in an episode of Horrible Histories.
Baynton tries to keep his children out of the spotlight. However he raised awareness about breaking gender stereotypes after his son was mocked in the park for wearing a pink bicycle helmet.[24] Baynton expressed his belief in letting his son express his likes and dislikes freely without assigning gendered stereotyping to toys and colours in. He stated "I won't be teaching my boy how to be a 'boy'."[24]
