A BRUSH WITH GENIUS By Jane Cameron Playing Vincent Van Gogh stretched actor Linus Roache to the limit, a role that he found "gruelling, but also wonderful" Nowadays his works sell for millions, but when Vincent Van Gogh died 100 years ago, he had sold just one painting. Interpreting such a gifted man was a daunting prospect for 26-year-old Linus Roache who plays the artist in the Omnibus dramatisation of Van Gogh's life. "Trying to reinhabit his life and do it justice is such an enormous responsibility", says Roache. "And there was a problem in my mind about playing him as a 37-year-old (Van Gogh's age when he died). That seemed such a long way from me. Then I realised it wasn't that different and the important thing was to tell of his journey as a man." Director Ana Benson Gyles - whose previous work includes 'Journey into the Shadows', a portrait of the artist Gwen John (with Anna Massey), and 'Stanley' a Screen Two play about artist Stanley Spencer - was very impressed by Roache. "So much has been written about Van Gogh that trying to find the man among the myths was quite a task for Linus," she says. A task that can hardly have been eased by the fact that the story wasn't shot in chronological order. Roache had to dip into Van Gogh's complex character almost at random. "I did find it very gruelling," admits Roache, "but also wonderful." The story is told in an impressionistic way and plays with time, weaving between Van Gogh's childhood in Holland, and his last days in Provence and Auvers. "Like showing pieces of a canvas," says Benson Gyles, "and eventually revealing the whole painting." It also interweaves with Roache's own life, as the painter's mother is played by Anna Cropper, Roache's real mother (his father is William Roache, 'Coronation Street's' Ken Barlow). Roache is currently playing Edgar in 'King Lear' and the title role in 'The Last Days of Don Juan' at Stratford. Next month he can be seen in a BBC2 'ScreenPlay' as a severely handicapped young man in 'Keeping Tom Nice'. He would have liked to have spent longer on Van Gogh. "I read his letters - he wrote three huge volumes to his brother Theo. I could have gone on studying him for years."
