YOU can now enjoy the adventures of one of the country's best-loved detectives in the heart of the Sussex countryside from the comfort of your own home.

Sir Ian McKellen's Mr Holmes, which was shot at locations such as Seaford Head, Seven Sisters, Seaford Beach and Hailsham’s vintage Pavilion Cinema, will be out on DVD and Blu Ray on October 26.

Director by Bill Condon, it tells the story of Sherlock Holmes aged 93. He has retired to a farmhouse in the Sussex countryside, which was filmed at Wickham Manor, near Rye.

With his best cases behind him he is trying to piece together his final mystery as he comes to terms with his failing mind.

The film's setting in Sussex is fitting as Sherlock Holmes creator Arthur Conan Doyle lived out the last of his days at Windlesham Manor in Crowborough.

Sir Ian, who plays the ageing super sleuth, told of how when he was researching the character he discovered there have been more than 150 film versions.

He said: “That’s a lot but it shows that this is a character that people are endlessly fascinated by.

“I suppose that it is an invention that struck some sort of chord with people. I can’t remember a time when I didn’t know who Sherlock Holmes was. I don’t remember being introduced to him; he’s always been there.

“That seems to have been true for a lot of people, and not just people who can read English books, which is where it all began. What’s interesting is that he was so clearly a man of his time, but you can remove him from his time and he remains himself.”

The film is based on Mitch Cullin’s acclaimed novel A Slight Trick of the Mind and features Holmes struggling to come to terms with early dementia.

Watson, Mrs Hudson, Mycroft, and Inspector Lestrade, are all gone and the 93-year-old detective’s only company is his housekeeper, played by Laura Linney, and her son Roger, played by newcomer Milo Parker.

The now 75-year-old Sir Ian said: “Old age, if you’re 75, is of interest to you. Some people never reach it, of course, and I had contemporaries who are dead.

“Some are struggling towards it with dreadful illnesses, and some people seem to be immortal, and each day is a new blessing.

“So I just think of Sherlock Holmes as an old man, really – coping, and coping better than most.”
