Shipwreck, which will officially open Dec. 21, begins in Moscow 13 years after the first part, Voyage, and follows the characters to Paris, Dresden and Nice.

Though Voyage had to delay its opening night to Nov. 27 because of actor Richard Easton's medical procedure, the rest of the trilogy's schedule is unchanged. Part three, Salvage, which takes place over 12 years in London and Geneva, begins previews Jan. 30, 2007, and opens Feb. 15.

All three parts will continue running, in repertory, until the end of the entire trilogy on March 10. On three Saturdays — Feb. 24, March 3 and March 10 — theatregoers will be able to see all three plays in one-day marathons.

The Coast of Utopia tells the story of a group of 19th-century Russian intellectuals who debate politics and philosophy and struggle to change their political system.

The eight-hour trilogy, directed by Broadway veteran Jack O'Brien (Hairspray, The Full Monty, Henry IV), boasts a cast of 44, including Billy Crudup, Richard Easton, Jennifer Ehle, Josh Hamilton, David Harbour, Jason Butler Harner, Ethan Hawke, Amy Irving, Brían F. O'Byrne and Martha Plimpton.

The play has sets by Bob Crowley and Scott Pask, costumes by Catherine Zuber, lighting by Natasha Katz, Brian MacDevitt and Kenneth Posner and original music and sound design by Mark Bennett.

The Vivian Beaumont Theater is located in Manhattan at 150 West 65th Street in Lincoln Center. For tickets or more information visit www.coastofutopia.com.
