Emma Angel of Angels Fancy Dress with the Obi-Wan cloak

After Guinness wore the garment for his role as Obi-Wan Kenobi, it was returned to British costume firm Bermans.

The cloak was subsequently loaned to other films including 1999's The Mummy, and even hired out as fancy dress.

It was identified in a stock check earlier this year and now forms part of a film memorabilia exhibition at the Harrods department store in London.

Director George Lucas divided the filming of his 1977 sci-fi classic between Tunisia and the Elstree and Shepperton studios in England.

Inventory

A number of costumiers were commissioned to provide items of clothing, including the cloak Obi-Wan wears for his lightsaber duel with Darth Vader.

The cloak formed part of Bermans' inventory when it was taken over by Angels the Costumiers in 1992.

It was worn by Sir Alec Guinness in the first Star Wars film

As such, it may also have featured in Sean Connery's 1986 film The Name of the Rose.

Authenticated by Star Wars' costume designer John Mollo, the cloak now forms part of the Brit-ish exhibition running at Harrods until 15 October.

Other items on display include costumes from Four Weddings and a Funeral, Shakespeare in Love and the Pink Panther films.

According to the Times, it is estimated to be worth £15,000 but could fetch as much as £25,000 at auction.

However, a spokesperson for Angels Fancy Dress said there are no plans to sell the item at this time.
