Domnhall Gleeson (Run) has been cast in the HBO five-part limited series The White House Plumbers, based on the 1972 Watergate scandal. Gleeson will co-star alongside the previously cast Woody Harrelson (Three Billboards Outside Ebbing, Missouri) and Justin Theroux (The Mosquito Coast), as reported by Deadline. 

Gleeson will portray John Dean, a former attorney who served as White House Council for Richard Nixon during his presidency from 1970 through 1973. Dean’s name became stained with notoriety as he was involved in the cover-up of the Watergate scandal, one of the biggest political scandals in American history. 

Gleeson is currently starring in Frank of Ireland, a Channel 4 and Amazon series. He co-wrote the show with his brother Brian Gleeson (Love/Hate) who stars alongside him. Also known for his role in the Harry Potter series, Gleeson played Ron’s older brother Bill Weasley. He also garnered attention for his role in the Netflix Black Mirror episode, “Be Right Back.” 

Harrelson will be stepping into the shoes of E. Howard Hunt and Theroux will be playing G. Gordon Liddy. Both worked for President Nixon during his presidency, and plotted the Watergate scandal together. In addition to starring in the show, both Harrelson and Theroux will co-executive produce. 

The upcoming series marks the three actors return to HBO. Gleeson just starred in the limited series Run opposite Merrit Weaver (Godless), which ran throughout the spring of 2020. Harrelson played the lead role in the critically acclaimed first season of True Detective in addition to executive producing the series. And Theroux  starred in The Leftovers, which ran from 2014 to 2017 and consisted of three seasons. 

Also returning to HBO are Veep writers and executive producers Alex Gregory (King of the Hill) and Peter Huyck (King of the Hill). For The White House Plumbers they will serve as the series showrunners and co-executive producers. David Mendel (Curb Your Enthusiam) will also executive produce and direct all five episodes. The series will be in part based upon public records of the Watergate scandal in addition to the novel Integrity written by Egil Krogh, an official for the Nixon administration at the time, and Matthew Krogh.
