With her fixer-upper penthouse on the Upper West Side of Manhattan having failed to entice a serious buyer after 10 long months on the market with a much-too-bullish asking price of almost $5.5 million, Penny Marshall has switched real estate agents and slashed the asking price to just below $4 million. The seventysomething, Bronx-born showbiz veteran acquired the approximately 1,800-square-foot penthouse some time in the early 1980s for an unknown amount.

The two-bedroom, two-bath aerie, in need of a comprehensive spruce up, sits atop a full-service prewar building and opens from a semi-private elevator landing to a spacious foyer accentuated by a stained-glass transom window. The combination living/dining room stretches elegantly to nearly 28 feet, with an 11-plus-foot beamed ceiling, herringbone-patterned hardwood floors, an unusually embellished fireplace flanked by slender built-in bookshelves, and French doors that open to a wraparound terrace of more than 1,000 square feet with a through-the-buildings view of the Hudson River. The kitchen is large enough to accommodate a dining table, and the master bedroom has several closets, terrace access through French doors, and an oversized ceramic-tiled bathroom with a fireplace behind the soaking tub.

Property records reveal the “Laverne and Shirley” star turned movie director (“Big,” “A League of Their Own”) and film producer (“Bewitched,” “Cinderella Man”), who’s rarely seen without a signature pair of tiny, pastel-lensed sunglasses perched at the end of her nose, has relocated to Los Angeles, where she owns a nearly 9,600-square-foot Mediterranean mansion behind gates on almost 1.5 acres in the Outpost Estates neighborhood in the foothills above Hollywood.
