• The novel was originally published as a short novella in Lippincott's Monthly Magazine in 1890, but it was heavily criticized by the magazine's editor for its immoral themes. Wilde was forced to revise and expand the novella into a full-length novel before it was published as a book in 1891.
• The novel was even more controversial after its publication as a book, and it was attacked by critics for its hedonism, homosexuality, and other subversive ideas. Wilde was eventually put on trial for gross indecency, and he was sentenced to two years in prison.
• The novel has been adapted into numerous films, television shows, and stage productions over the years. Some of the most notable adaptations include the 1945 film directed by Albert Lewin, the 1970 film directed by Tony Richardson, and the 2003 film directed by Oliver Parker.
• The novel has also been the subject of much scholarly analysis and interpretation. Some critics have seen it as a cautionary tale about the dangers of vanity and hedonism, while others have seen it as a celebration of art and beauty.
• The novel is full of interesting symbolism and imagery. For example, the portrait of Dorian Gray can be seen as a symbol of his conscience, while the locked attic where he keeps it can be seen as a symbol of his repressed desires.

Here are some more specific interesting facts about the novel:

• The character of Lord Henry Wotton is based on Wilde's close friend, the philosopher and writer Walter Pater.
• The idea for the portrait that ages instead of the protagonist was inspired by a story Oscar Wilde heard about a youth who sold his soul to the devil.
