Line of Duty star Adrian Dunbar is set to star on ITV's DNA Journey to uncover details of their ancestry which will air later this year.
The Irish actor, 64, starred alongside Scots star Martin Compston and Vicky McClure on the BBC cop drama which is set for a big return soon. Alongside Dunbar, Downton Abbey star Hugh Bonneville and comedian Johnny Vegas are also set to uncover their past on the fourth season of DNA Journey.
The Ted Hastings actor will pair up with ex-Men Behaving Badly star Neil Morrissey, 60, who has Irish ancestry, to find out all about their past.
Bonneville, 59, who lives in West Sussex, will be paired with Doctor Who star and comedian John Bishop, 56. Strictly Come Dancing star Oti Mabuse and her older sister Motsi Mabuse will team up to uncover the truth behind their bloodlines using the show’s DNA technology and genealogy expertise.
The two ballroom dancers, who are from South Africa, moved to Germany and appeared on the country’s version of Strictly Let’s Dance before joining the celebrity dancing series on the BBC.
ITV's head of entertainment commissioning, Katie Rawcliffe, said in a statement: "DNA Journey delves deep into the celebrity's family history and has unearthed some astonishing revelations over the last few years.
"It's great to see these famous faces sharing their journey with each other and we've got another great line-up with some more fascinating surprises."
The third series of the show featured the Dancing On Ice stars Jayne Torvill and Christopher Dean, alongside Coronation Street actors Maureen Lipman and Rula Lenska, and The Chase quizzers Anne Hegerty and Shaun Wallace.
Comedians Rob Beckett and Romesh Ranganathan, Gavin and Stacey's Alison Steadman and Larry Lamb, comics Joel Dommett and Tom Allen, and presenters Alison Hammond and Kate Garraway also took part to uncover their past.
DNA Journey returns to ITV and streaming service ITVX later this year.
