The Inglourious Basterds actor, who has a long held interest in architecture, arrived at Zadar Airport last Thursday (02Sep16) dressed in an all white outfit and matching hat, for a whistle-stop tour of the proposed project site. The ambitious project plans to transform both land and an existing marina site into a resort that features a flagship luxury hotel, shops and villas.

Schools and a clinic are also included in the plans, which will potentially house a community of 2,500 at a reported cost of $1.5 billion (£1.1 billion).

According to editors at People.com, Pitt stayed overnight in the locale's recently opened waterside Dogusevom Hotel, designed by architect Nikola Basic, who later led Pitt and a group on a walking tour around the proposed project site in Zablace.

Basic also created Zadar's celebrated Sea Organ quay design, a giant sculpture that plays music created by sea waves passing through tubes beneath its large marble steps, and is creatively leading the plans at Zablace.

Pitt's involvement in the project is bound to be more than just observational. The Mr & Mrs Smith actor has a sustained interest in architecture, and took a break from Hollywood to study computer-aided design at the Los Angeles offices of renowned architect Frank Gehry.

In a 2004 interview with Vanity Fair Pitt said: "I'm really into architecture, structure and design. Give me anything and I'll design it. I'm a bit nutty with it." Pitt added: "I've got a few men I respect very much and one would be Frank Gehry. He said to me, 'If you know where it's going, it's not worth doing.' That's become like a mantra for me. That's the life of the artist."

In 2006 he founded the Make It Right Foundation to galvanise housing professionals in New Orleans to finance and construct 150 sustainable, affordable new houses in New Orleans's Ninth Ward, following the devastation caused by Hurricane Katrina.

Pitt first visited the Dalmatian coastal region in 1988 to film Dark Side of the Sun in both Yugoslavia and Montenegro.
