Actor Alfie Allen appeared on Good Morning America April 13 to discuss his role in Martin McDonagh's Hangmen, his upcoming television miniseries SAS: Rogue Heroes, and how he is adjusting to life in New York ahead of his Broadway debut.

Hangmen, originally supposed to open on Broadway in 2020, will officially open April 21 at the Golden Theatre. Performances began April 8.

The company of Hangmen includes Allen, two-time Olivier winner and Tony nominee Tracie Bennett (End of the Rainbow, Follies), Owen Campbell, Jeremy Crutchley, Olivier Bursary Award winner Gaby French, Josh Goulding, John Hodgkinson, Richard Hollis, John Horton, Andy Nyman, and Ryan Pope, with Sebastian Beacon, Peter Bradbury, Gina Costigan, Katie Fabel, and Colin McPhillamy. Tony nominee David Threlfall (Nicholas Nickleby, Shameless) leads the company, back on Broadway after a 25-year absence. 

Matthew Dunster directs the Royal Court Theatre/Atlantic Theater Company production, which centers on on Harry (Threlfall), a hangman who finds himself unemployed when hanging is abolished. Set in a small pub in Northern England in the 1960s, regulars gather to hear Harry's reaction to the news when a mysterious stranger from London, Mooney (Allen), enters their world.

Hangmen features set and costume design by Olivier winner Anna Fleischle, with lighting design by Joshua Carr and sound design by Olivier Award winner Ian Dickinson. Casting is by Amy Ball and The Telsey Office's Adam Caldwell. Robert Fox, Jean Doumanian, and Craig Balsam produce.
