Three Days of Rain is a play by Richard Greenberg that was commissioned and produced by South Coast Repertory in 1997. The title comes from a line from W. S. Merwin's poem, "For the Anniversary of My Death" (1967). The play has often been called Stoppardian but Greenberg says he wasn't aware of Stoppard's work before he wrote the play but instead claims 1967 BBC series The Forsyte Saga was a much greater influence.^[1] Three Days of Rain was nominated for the 1998 Pulitzer Prize for Drama.

Walker^[2] and his sister Nan met in an unoccupied studio in lower Manhattan in 1995. Walker, who had disappeared the day after his father's funeral, now months later is living in this apartment where his father, Ned Janeway and business partner, Theo Wexler, once lived and worked designing the famous "Janeway House". Walker has found their father's journal and attempts to use it to understand the relationship between Ned and Theo. Nan and Walker's childhood friend Pip (Theo's son) meets with them after the reading of Ned's Will, where the three have learned that Janeway House was left to Pip rather than Ned's children. Walker is furious and accuses Pip of "working on" Ned to bequeath him the house. Pip denies this and protests that he does not understand why the house was not left to Nan and Walker as next of kin. Pip reveals that he doesn't even like the house, which prompts another tirade in Walker. Fed up with Walker's ranting, Pip fights back at Walker verbally. Pip accuses Walker of secretly being in love with him for 18 years and reveals that he (Pip) and Nan were secretly sleeping with one another (behind Walker's back) when they were young. Walker runs off into the night. Pip says he may have gone too far and agrees with Nan to sell Walker the house. Nan tries to find Walker to tell him. Distraught when unable to find him, Nan decides to stay at the studio until he returns. After Walker returns, Nan apologizes and the two of them continue to parse Ned's concise and mysterious journal which opens with the entry: "1960, April 3–5. Three days of rain". Walker believes he's found a confession from Ned, hidden within the pages of the book, to the effect that Ned took credit for Theo's work on the house after Theo's death in 1966. Nan does not accept this interpretation but acquiesces to calm her brother. She tells Walker that Pip would sell him the house, but Walker's new-found "revelation" changes his mind about wanting it. Walker burns the diary, much to Nan's chagrin.

The second act shifts to an earlier time, with the same three actors portraying members of the previous generation in the same studio apartment, during April 1960 when Janeway House was designed. The actor portraying Walker becoming Walker's father Ned, the actor portraying Pip becoming Pip's father Theo, and the actor portraying Nan becoming Nan and Walker's mother, Lina. The assumptions made in the first half about the parents are shown to be wildly inaccurate. Ned is not the callous, silent patriarch he seemed to the children. Instead he is a shy stutterer, who, while an immensely talented architect, has trouble making eye contact or holding a conversation with anyone. Theo is revealed to be a charismatic man, more concerned with fame and the idea of art, than the creation of any original art itself. Lina, a bohemian southern belle, is dating Theo and their arguments are loud enough to inform the entire neighborhood. Theo and Ned attempt to design a house commissioned by Ned's parents, but Ned recognizes Theo's design as plagiarizing an existing house. Ned and Theo fight, and Theo leaves for a few days to try to work in solitude.

A few days later, Ned runs into Lina during a rainstorm, and they return to the apartment to escape the downpour. Ned invites Lina to stay for dinner, which leads each to reveal issues plaguing them. Lina resolves to leave before succumbing to Ned's unintentional shy sweetness, only to overhear Ned practicing telling Lina that he secretly loves her. Lina confronts Ned, and they spend three days in bed. Theo returns earlier than expected from his work retreat, finding Ned and Lina together in the apartment. He is embarrassed and leaves, with Ned trailing him. Ned attempts to apologize, but learns Theo is upset not about Lina but about failing to return with an original design. Lina persuades Ned that Theo will be okay, and that Ned should apply his emotions to draw the house she knows he imagines. He sits down to draw, suggesting that it was he who designed Janeway House and not Theo, as Walker had concluded.

Walker/Ned Walker: A quirky and unstable young man, haunted by what he sees as a destructive and unloving relationship with his parents. He has a habit of disappearing suddenly in order to avoid dealing with real life. Ned: Walker and Nan's father who, despite his son's depiction of him as cold and uncaring, was in his youth a stuttering, shy, and talented architect.

Pip/Theo Pip: A proudly naïve TV actor and family friend of the Janeway's. Handsome, and not as dumb as he looks, he is constantly frustrated by others taking their lives so seriously, and can't fathom why people see the need to incite drama. Theo: Pip's father and Ned's business partner. A very charismatic man who is more interested in fame and the accolades that come with it than creating the art that would earn it.

Nan/Lina Nan: A practical, kind woman. Caring about her family and friends, she finds it difficult to balance her frustration at her brother Walker's craziness and Pip's naiveté. Lina: Nan and Walker's mother. A southern belle, easily changeable and tempestuous, beginning to show some of the signposts of mental instability.

The Steppenwolf Theater Company produced the play opening February 11, 1999. It starred Tracy Letts, Amy Morton and Ian Barford and was directed by Anna D. Shapiro.^[8] The Chicago Tribune review states that "In Three Days of Rain, Greenberg has constructed an almost perfect showcase for his considerable talents, and Steppenwolf has responded with a director, Anna D. Shapiro, and a cast – Tracy Letts, Amy Morton and Ian Barford – that gives his script a lovely, burnished glow in performance."^[9]

Arguably the most famous production to date^{[according to whom?]} was on Broadway, with Julia Roberts making her stage debut. Ben Brantley, The New York Times reviewer wrote: "And though Ms. Roberts gives a genuinely humble performance, there is no way that this show is not going to be all about Julia."^[10]

Opening in April 2006 at the Bernard B. Jacobs Theatre, Roberts co-starred with Paul Rudd and Bradley Cooper. Although it may have been the most eagerly awaited show of the Broadway season in the popular press, it met with poor response from theatrical reviewers and closed as scheduled in June 2006.^{[citation needed]} The New York Times reviewer summed up the experience: "Some movie fans may have the same fear about seeing Ms. Roberts in the flesh. They shouldn't. She looks every inch the magnetic (if theatrically challenged) movie star. Fans of Mr. Greenberg, on the other hand, should definitely stay home."^[10]
