The former "X-Files" star opens in Rebecca Gilman's The Sweetest Swing In Baseball at the Royal Court Theatre March 31.

In the play, Anderson portrays Dana, a successful artist. Until, that is, her new exhibition drops like a stone and she enters a psychiatric hospital. In the hospital she is safe, but her insurance company tells her she can only stay for ten days — and to get through the ordeal Dana becomes inspired by the story of baseball's Darryl Strawberry. Coincidentally, Anderson's part in What The Night Is For also saw her playing a character battling with mental health problems, as a manic depressive.

Playwright Gilman is a Royal Court regular. Her previous plays there have included Boy Gets Girl, Spinning Into Butter and the award winning (Most Promising Playwright prizes at the Evening Standard and George Devine awards) The Glory of Living. She is, in fact, the only American ever to have won the Evening Standard gong. Royal Court artistic director Ian Rickson is at the helm, with designs by Hildegard Bechtler, lighting by Howard Harrison, sound by Ian Dickinson and music by Peter Salem.

In addition to Anderson, the cast includes Nancy Crane, Demetri Gontsas, Kate Harper and John Sharian. The show runs at the Sloane Square venue's Jerwood Theatre Downstairs until May 15.
