The official "Gone Girl" movie trailer went viral in YouTube as "How I Met Your Mother" cast Neil Patrick Harris delivers a haunting performance as Desi Collings.

The "Gone Girl" movie trailer was uploaded in the social media site and so far generated more than half a million hits.

The "Gone Girl" movie is based on the novel of the same title by Gillian Flynn. She also wrote the screenplay, which would be interesting to see whether he will follow the trajectory of the characters in the book or not.

In a Reddit AMA interaction with fans, Gillian Flynn said: "Of course, the script has to be different from the book in some ways-you have to find a way to externalize all those internal thoughts and you have to do more with less room and you just don't have room for everything. But the mood, tone and spirit of the book are very much intact."

London's The Guardian noted the controversy in the casting, particularly on choosing Rosamund Pike over bigger names such as Charlize Theron, Olivia Wilde and Natalie Portman. The furor increased with the announcement that Tyler Perry will play the lawyer Tanner Bolt.

The "Gone Girl" movie trailer also shows a very different Neil Patrick Harris, no more legen-wait for it-dary punchlines as Barney Stinson in "How I Met Your Mother."

Neil Patrick Harris plays Desi Collings, the former boyfriend of Amy Dunne and the prime suspect in Nick's mind. Although to be fair, Nick thinks everybody's guilty but him.

In fact, the New York Post called the attention of viewers on the performance of Neil Patrick Harris, who is more known for his comedic chops than in drama.

"It was already one of the year's most anticipated movies, but now 'Gone Girl' has gone and upped the ante with a special ingredient: a sunken-eyed Neil Patrick Harris," it said.
