Dyer described it as a "mad riddle that no one knows what it is" and called the former Prime Minister of the United Kingdom, David Cameron, a "twat". In August 2018, Dyer began narrating MTV reality series, "True Love or True Lies". In 2019, Dyer appeared in a history documentary, titled "Danny Dyer's Right Royal Family". The two-part series premiered on BBC One on 23 January 2019. Dyer is best known for his "bad boy" or "hard man" roles in film. Dyer's first film role was in "Human Traffic" (1999). His subsequent movie work includes Mel Smith's "High Heels and Low Lifes" (2001) and starring roles in "Borstal Boy" (2000), "Mean Machine" (2002) and in four films by the British film director Nick Love: "Goodbye Charlie Bright" (2001); "The Football Factory" (2004); "The Business" (2005); and "Outlaw" (2007). Among other film roles, he also appeared as the character Steve in Christopher Smith's "Severance" (2006); as Hayden in "Adulthood" (2008); and as himself in the feature documentary "Tattoos: A Scarred History". In 2008, he finished filming his roles as Pete and Tom in "City Rats" and "7 Lives", respectively. April 2009 saw the straight to DVD release of "City Rats". Later that year, Dyer completed filming on "Jack Said", a Brit noir thriller in which he played Nathan alongside Ashlie Walker, Terry Stone, David O'Hara and Simon Phillips, which was released in November 2009. This film is the prequel to "Jack Says", which was released in 2008, and starred Mike Reid. In 2009, he shot several horror films including "Doghouse" under the direction of Jake West, and "Basement" under the direction of Asham Kamboj. He played one of the lead roles in the British vampire film "Dead Cert". In June 2010, he was cast for the lead role in the remake of the British horror film "The Asphyx", but it failed to secure production finance and was indefinitely shelved. Dyer co-starred with Anna Walton in "Deviation", a British dark thriller written and directed by J. K. Amalou. In 2012, Dyer played the lead role in Ray Cooney's "Run For Your Wife". Upon release in 2013, it was savaged by critics, who described it as one of the worst British films of all time.
