- Dorian is a scrawny dark-haired young boy... nothing like described in the book. Where are his golden locks and muscular physic?
- Colin Firth was another casting mistake. Although he looked similar to how I pictured Lord Henry Wotton, how could I possible picture him as a negative influence and overall pretty sleazy man, when I just watched Mamma Mia two days earlier?
- The movie opens with Dorian stabbing Basil over and over. Although I appreciate the dramatic aspect, it's a bit of a spoiler for people who haven't read the book.
- Basil's painting goes on display in the movie, and people love it. This contrasts the book, because Basil was adamant on not showing anyone the painting.
- Sibyl Vane doesn't kill herself by poison, but instead drowns... more on that later.
- Instead of indulging on materialistic items, the movie version of Dorian Gray expresses his lack of a soul by having a lot of sex. Definitely not my favorite montage.
- Basil and Dorian get very intimate in the montage mentioned above. Although there was hinting of that in the book, Wilde never came right out and said they were gay or bisexual.
- Although Dorian kills Basil exactly how it is described in the book, movie Dorian doesn't blackmail his house servant into disposing Basil's body. Instead, Dorian chops it into pieces then throws the pieces into a river, the same river Sibyl committed suicide in. That part was very hard to watch. On top of that, the pieces are found, and there is a hunt for the murderer (Dorian is never considered).
- Sibyl Vane's brother does try to kill Dorian twice, just like in the book. The first time the depiction is word for word, however, the second time it was much different. The short version is that James Vane chased Dorian on to train tracks, almost killed Dorian, then was hit and killed by a train. Nothing like the book.
- Not only does the painting age, but it literally comes to life. You can hear it moaning and groaning throughout the movie, and at one point it stretches out of the painting.
- One of the BIGGEST differences is that Basil has a daughter who falls in love with Dorian. Dorian tries to resist her charm, but fails. To say Basil was upset when he found out would be a severe under-exaggeration.
- The final scene is super dramatic, just like in the book, but the movie strays quite a bit from the original ending. Basil ends up confronting Dorian about his relations with his daughter, and sees the painting. Dorian tries to kill him in attempt to keep his secret, but fails, and Basil ends up locking Dorian in the attic and lighting it on fire. Dorian then says a tearful goodbye to his lady-friend (Basil's daughter), and confronts the painting at last. The painting, which is really gross at this point, emerges from the canvas while Dorian attempts to stab it. Finally, the painting smashes into Dorian's face at the same moment that Dorian plunges the sword though the canvas. The movie ends, just like the book. Dorian's lifeless body is shown looking really old and disgusting, and the painting returns to it's original state.
So if any of that confused you, I suggest watching the movie and reading the book for clarification. You probably won't regret it.
