Film actress Julia Roberts is to make her Broadway debut in a revival of Richard Greenberg's "Three Days of Rain", the New York Times reported.

Roberts, 37, who won a best actress Oscar for "Erin Brockovitch" in 2000, has barely any theatre experience and said she was nervous about the debut, said the report Friday.

"By the time I get there, I'll be entirely apoplectic," Roberts said. "But the terror is part of the excitement."

Played in two acts set 35 years apart, "Three Days of Rain" tells the story of a brother, a sister and a family friend delving into a secret at the heart of their parents' relationship. The actors play the children in the first act and the parents in the second.
