The star from 'Chilling Adventures of Sabrina' joins an already all-star cast for the limited series.

Kiernan Shipka has found her next role, starring opposite our own Domhnall Gleeson in the HBO watergate series 'The White House Plumbers'.

As reported previously, the five-part series will be a political dramedy from 'Veep' creators, all about the goings-on within the White House during President Nixon's reign. Kiernan will star as Kevan Hunt, the president of the Smith College Republicans and the reported "golden child" of the Hunt family.

Woody Harrelson will play her father in the series, E. Howard Hunt, alongside Justin Theroux as G. Gordon Liddy - both accidentally sabotaging the presidency they were trying to protect. Domhnall Gleeson has been cast as the man who spearheaded Nixon's demise, John Dean.

'Game of Thrones' actor Lena Headey has also joined 'The White House Plumbers' since the initial cast was announced. She'll star as Dorothy Hunt, Howard's wife.

Also added to the ever-expanding cast this week is David Krumholtz from 'The Santa Clause' and 'The Deuce', Ike Barinholtz from 'The Mindy Project', Yul Vazquez from 'American Gangster', as well as Rich Sommer from 'Mad Men', Kim Coates from 'Sons of Anarchy' and Liam James from 'The Way Way Back'.

Both Harrelson and Theroux are also on board as executive producers, with ‘Veep’ writers and executive producers Alex Gregory and Peter Huyck creating the HBO limited series. ‘Veep’ showrunner Davin Mandell is on board as executive producer and director. 

Since exiting 'Chilling Adventures of Sabrina' at Netflix after four seasons as the titular witch, Kiernan Shipka will also star in the upcoming 'Swimming With Sharks' TV series. Based on the '90s movie of the same name, Kiernan's series will be a contemporary version of the behind-the-scenes happenings at a Hollywood studio. She'll play a young assistant opposite Diane Kruger and Ross Butler.
