Former "JAG" star David James Elliott has been tapped to star in "Impact," a four-hour disaster miniseries from Muse Entertainment, Jaffe/Braunstein Entertainment and Tandem Communications, says The Hollywood Reporter.

Budgeted at $13 million, the effects-heavy "Impact" chronicles the aftermath of a meteor shower during which a piece of a dwarf star lodges itself in the moon. That triggers a series of anomalies on Earth, including cell phone service interruption, exaggerated tides and the occurrence of sporadic weightlessness.

Astrophysicist Alex Kinter (Elliott), with a help of a female astronomer, discover that the moon has been dislodged from its orbit and is on a collision course with Earth.
