Before you judge this movie
For those of you who you want to follow the trend of claiming this is an insult to Wilde's work, it's really not. Sure it changed a few things but think of the far worse versions of Dorian out there.
League of Extraordinary Gentlemen: Implied he was from a long family of people who bound themselves to portraits (novelization). And he couldn't even look at his picture without dying. This caused a long running belief that lingers today where many people think he can't look at his painting without dying. It also made him far older, dark haired with a gotee, and a college lecturer.
Sins of Dorian Gray: Made Dorian an actress in the 1980s.
Picture of Dorian Gray: I can't recall if this is from 2004 or 2006. Set in the 1960s it has a female Basil and very bad acting.
Dorian Gray: This 1970 film is a porn. That's it.
Picture of Dorian Gray: 1973: This version has Dorian cold through the whole thing, never innocent. He is blackmailed by James Vane and ends up marrying Basil's Canadian niece, Beatrice. Like the 1935 film this version has Dorian dump Sibyl after he's seduced her into sleeping with him, and like with this newest version, she drowns herself instead of taking poison. Also there's a very drawn out scene of Dorian blackmailing Alan Campbell WHILE applying jam to many small pieces of bread as he's laying in bed eating breakfast.
Picture of Dorian Gray: BBC made for TV version. This version has a Dorian that looks like he's twelve-years-old. There's a huge time jump toward the middle without anything to tell you a great deal of time has passed. The acting is horrible. (See the clip on youtube of when he finds out Sibyl's dead). Sibyl's very appearance is more than two thirds into the story to tell you how badly paced it is. The painting isn't even that hideous. He looks like a pale, older man. Oh, no, he looks fiftish! It's hideous!
Out of all the film versions of Dorian Gray I've seen this 2009 version is most true to the heart of Oscar Wilde's novel and his original intent. The 1935 version comes close second.
You want to see a miserable insult to Oscar Wilde, go see the 1940s version of The Canterville Ghost, some time. The most faithful version of that, by the way, is the one with Patrick Stewart. Though modernized, it's very true to Wilde's story.
So next time you think something ripped apart a novel, think twice, look at the other adaptations. Consider not the literal content of a story, but also the spirit and intent.
