NBC's "Revelations" (search) booked solid premiere numbers Wednesday against Fox's "American Idol" (search) juggernaut.

The spiritual drama, starring Bill Pullman, snared 15.6 million viewers vs. "Idol" from 9 to 10 p.m. EDT — NBC's best numbers in that timeslot since a special "Law & Order" last September.

While "Idol" dwarfed "Revelations" by nearly 9 million viewers, the drama — scheduled for a six-episode run — increased NBC's 18-49 timeslot demo numbers by 39 percent, and built on its "Dateline" lead-in across all categories.

In the series, Pullman plays Dr. Richard Massey, a Harvard professor who's also an astrophysicist convinced that all events can be scientifically explained.

But after his daughter is murdered, Massey's beliefs in science are shaken when he encounters a nun, Sister Josepha Montifiore (Natascha McElhone), who leads him on a spiritual path.
