Lagerfelt, who made her stage debut at London's Royal Court in the premiere production of Christopher Hampton's The Philanthropist, subsequently reprised the play for its Broadway premiere in 1971, and has since appeared on Broadway in The Jockey Club Stakes, The Constant Wife, Otherwise Engaged, Betrayal, The Real Thing, Lend Me a Tenor and A Small Family Business. She was recently seen in the Tricycle's Off-Broadway transfer of Guantanamo: Honor Bound to Defend Freedom, also directed by Kent. TV credits include Ce Ce Rhodes in "Gossip Girl," Inger Dominguez in "Nash Bridges" and Sheila Silver in "Beverly Hills 90210." Film credits include "August," "Poseidon," "All the King's Men" and "Minority Report."

According to press materials, the play is set in 1967, when Garbo did indeed come to Donegal in Ireland – and nothing was ever the same afterwards. "Ireland is on the verge of violent change, two couples are on the verge of ending, a woman tries to save her family, a girl tries to save her future. Above it all but in the midst of things, determining what happens next, is the loveliest and loneliest of all women, the great Garbo. But when the gods arrive, they can cause havoc, not least to themselves, as the divine Greta learns."

The cast also includes Angeline Ball (seen as Imelda Quirke in "The Commitments"), Lisa Diveney (seen in the Donmar Warehouse production of John Gabriel Borkman) Michelle Fairley (previously seen at the Tricycle in Hostage and The Factory Girls, and last seen on the London stage in Dancing at Lughnasa at the Old Vic), Daniel Gerroll (who has appeared at the Royal Court), Owen McDonnell (most recently on the London stage in Berlin Hannover Express at Hampstead Theatre) and Tom KcKay (seen earlier this year at the Tricycle as part of the company for The Great Game: Afghanistan).

Director Nicolas Kent last directed The Great Game: Afghanistan at the Tricycle, where his previous productions also include The Great White Hope, Trouble in Mind, Wine in the Wilderness, A Love Song for Ulster, Macbeth and all the Tricycle's Tribunal Plays that replay important public enquiries as dramas. The production is designed by Robert Jones with lighting by Matthew Eagland and sound by Tom Lishman. Playwright Frank McGuinness' other plays include Observe the Sons of Ulster Marching Towards the Somme, Someone Who'll Watch Over Me, Gates of Gold and The Factory Girls. He has also translated Helen (seen at Shakespeare's Globe this year) and Oedipus (for the National Theatre).
