There are no Signs on the lawn, but I have it on Unbreakable authority that filmmaker

M. Night Shyamalan's

Gladwyne estate is being offered for $8 million.

A Sixth Sense at work? Not at all. Real-estate agents last week took a private tour and were left Wide Awake by the seven bedrooms, nine full baths (and two partial baths), two offices, playroom, movie theater, swimming pool and 20-foot slate waterfall (but no Lady in the Water).

The house, on nearly two acres, has nearly 13,000 square feet of living space, according to the description.

Montgomery County records show the Shyamalans paid $4.5 million when it was built in 2000. They've been spending more time at their own personal Village - a très privé 123-acre compound in Willistown Township for which he paid $17.9 million two years ago.

Shyamalan, 36, is in preproduction for his latest shot-in-Philly film, The Happening. He also is due as a guest Friday at a benefit to be held at Sherman Mills East Falls for Steppingstone Scholars, which prepares urban kids for college-prep schools.

Good sport

, who played basketball and field hockey for the top-ranked teams at Flourtown's Mount St. Joseph Academy, will be the youngest member of the cinematic 1972 Immaculata Mighty Macs basketball squad when it suits up later this month to film

Our Lady of Victory

. Meghan, 18, wowed casting people by wearing a 1970s-era red jumper borrowed from a friend of her mother's. Meghan heads to St. Joseph's University in the fall, but the movie role means that she is ineligible now or in the future to play on a Division I or II team.

Briefly noted

Sixers broadcaster

Marc Zumoff

finished his first Broad Street Run on Sunday, and his 1:28.49 time beat his 1:30 target. His favorite sign: "If you're not throwing up, you're not running hard enough."

Singer-songwriter Jill Scott ran late to Sunday's Black Lily Honors ceremony, at which the Greater Philadelphia Tourism Marketing Corp.'s "uwishunu" campaign was to give her the Artistic Achievement Award. Scott did sing at the post-ceremony concert at World Cafe Live, where surprise guest Amy Winehouse performed two songs. Black Lily is a film and music festival celebrating women's work in these mediums.

TV notes

CBS3 anchor

Larry Mendte

and a crew will be at Arch Street United Methodist Church at Broad and Arch Streets at 6 p.m. today to tape the choir performing "Amazing Grace" for a Memorial Day special about a local soldier who gave Beanie Babies to Iraqi children. Veterans and families of vets (especially those now serving in Iraq) can show up and talk on camera.

Dannon Green, who grew up near Overbrook High, will crack wise on Martin Lawrence Presents 1st Amendment Stand-up at 11:15 p.m. tomorrow on Starz. Green's most recent work includes four episodes of Everybody Hates Chris.

A costumed Spider-Man, brought to Fox29's Good Day Philadelphia yesterday to talk up the movie's boffo opening-weekend box office, caused a mild ruckus. Cohost Clayton Morris' spider senses began tingling when the out-of-shape impersonator, prattling on about Barsky's midday show on Free FM, stood on the anchor desk - and threatened to expose more than his, um, superpowers. Morris dramatically leaped to the camera and, suppressing a laugh, begged for a commercial break. Ah, live TV.
