Signature Properties not only got beautiful weather for a party to open its new Cold Spring Harbor location but some unusual entertainment: As revelers sipped martinis on the back deck behind the 99 Main St. office, HBO filmed scenes for its upcoming miniseries "Mildred Pierce."

But while party-goers whispered that star Kate Winslet would be there for the Spring Street shoot, she was nowhere to be found.

"So much for that," said Barbara Wanamaker, broker/owner with developer and co-owner Peter Morris of the local independent agency, which has two other offices in Huntington and has been open since 2007.

Winslet was apparently nearby, said a production hand setting up the shoot, which involved driving an old-fashioned car up and down the rustic street. In fact, someone at the party said Winslet had been spotted by her teenage daughter filming the night before at the Cold Spring Harbor Beach Club up the road.

HBO has been shooting at various locations on the North Shore, including the Woolworth mansion in Glen Cove. Winslet is said to be filming this weekend in Bayville.
