Hollywood can't help but turn popular books into movies. Just look at what they've done recently: Twilight, The Hunger Games and now Fifty Shades of Grey. Sometimes the films are box office hits (see the Harry Potter franchise), and sometimes they bomb (see 2012's John Carter).

Still, we get excited when we hear one of our favorite books is being turned into a movie. Here are three of our favorite books-turned-movies that are expected to release in theaters this year.

Thirteen Reasons Why by Jay Asher
Clay Jensen is a nice, shy, ordinary boy who had a huge crush on Hannah Baker, the girl who committed suicide. However, before she died, Hannah made cassette tapes that explain the reasons why she chose to commit suicide: 13 reasons, 13 different people and 13 different situations that impacted her life. Clay was one of those reasons.

The book follows Clay as he goes to all of these different places and tries to figure out the part he played in Hannah’s death. By listening to the tapes, Clay also finds out the identity of the other 12 people, and it is changing his perspective of his peers.

This book has captivated many and will be portrayed in a film. Rumors state Selena Gomez will be playing Hannah Baker, and Logan Lerman (Percy Jackson movies) will play Clay Jensen. The release date is unclear, because this movie is still in pre-production.

Personally, I don’t picture Gomez as Hannah, but Jay Asher has said he sees potential in Gomez, and well…who knows Hannah better than he?

I do, however, picture Logan Lerman as Clay. If The Perks of Being a Wallflower was any indicator, Lerman could play the nice, shy guy quite well.

The problem I have with this book becoming a film would be the time sequence. There are many flashbacks and flash forwards; how will that be portrayed without confusing the audience?

Divergent by Veronica Roth
This series is nothing like The Hunger Games. Yes, it's set in a dystopian era, and the characters are on the brink of war, but those are the only similarities.

Divergent is about 16-year-old Beatrice Prior who is about to choose whether she wants to stay with her family or go to a different faction. Factions are like communities. There are five different factions: Abnegation, Dauntless, Amity, Candor and Erudite, and each has their own virtue of some sort. Abnegation is all about selflessness, Candor is about pursuing the truth, Dauntless is about being brave, Amity is about being peaceful, and Erudite is about knowledge.

Beatrice was born Abnegation, but she always thought she wasn't selfless enough, and that's what has her contemplating changing factions.

When she goes into her testing simulation, Beatrice finds out that she is Divergent. This means she recognizes she is under simulation, putting her in danger and changing her world completely.

The book has some romance and life-threatening scenes that help catapult you into its amazing story.

Shailene Woodley (“The Secret Life of the American Teenager”) will be portraying Beatrice, alongside her romantic counterpart Four, who will be portrayed by Theo James (Underworld: Awakening). Miles Teller (That Awkward Moment), Ansel Elgort (Carrie) and Kate Winslet will also be starring in this film.

I'm curious to see how the book looks on the big screen. James is not a newcomer, and I think he can pull of Four. Woodley, on the other hand, will be out of her comfort zone as she takes on a role we’ve never seen her portray.

The trailer has kept all of us anticipated for this film and has given us some insight on their acting.

Overall, the film will satifsy the book's fanbase.

The Fault In Our Stars by John Green
John Green's The Fault in Our Stars is by far one of the best books I have read as of late.

Hazel Grace Lancaster and Augustus Waters meet at a cancer support group through their mutual friend Lucas. Their relationship starts to blossom while they watch V For Vendetta and talk about books. Despite the fact Hazel carries an oxygen tank and Augustus has a prosthetic leg, their relationship grows stronger once they both develop a fascination with the book An Imperial Affliction.

As with every relationship, problems occur between Hazel Grace and Augustus, but the two find a way to make their love strong.

The storyline is captivating and makes you think of how precious time is. This is now one of my favorite books, and I am curious to see how the characters will be portrayed in the upcoming movie.

The movie will star Woodley (again) as Hazel Grace and Elgort (again) as Augustus. It’s scheduled to release on June 6.

Everyone interprets the story in his or her mind differently, but in my opinion, casting was selected perfectly. When I read the book, I did picture Woodley as Hazel Grace. Elgort is showing us he has what it takes in the new trailer. I am sure the film will stay true to the book.
