Everyone loves a good time travel story, and, thankfully, there have been dozens of awesome movies about time travel. In the 80s, there was the Back to the Future trilogy, in 2002, we had The Time Machine, and, when 2009 rolled around, The Time Traveler's Wife made its way onto the scene.

Henry was born with a genetic condition that causes him to time travel, and it comes with its share of problems. The Time Traveler's Wife was originally a book written in 2003 by Audrey Niffenegger. Like many good books, some things were changed and added to the story when it became a movie. Here are ten things from the movie that didn't happen in the book:

"Prove You're From the Future."

When Henry travels back to visit Claire for the first time, he meets her in the meadow behind her parents' house. She doesn't believe that he is a time traveler when she tells him. In the movie, he attempts to prove it by telling her that in a few days, her idiot brother Mark will fall out of a tree and break his arm. She says to him, "I won't know 'til then if you're telling the truth or not." In the book, this exchange does not take place, and Henry does not offer her a similar explanation as to how she can be convinced he is from the future.

The Dates

As a little girl in the book, Claire knows what days Henry is coming to visit her in the meadow because he gives her a list of dates. While in the book, Claire eagerly gives him this list in the present so that he can go back and give it to her in the past, it doesn't work quite the same way in the movie.

On-screen, Henry finds Claire's diary when he visits her apartment, and he flips through it to find the dates, knowing that she wrote down every time he came to visit. Claire sees him and gets upset, saying that her diary is private. He explains what he is doing, but we don't get to see if she willingly gives him the dates or not.

Waiting

Henry time travels a lot, and, in the present, there are often times where Claire finds herself alone waiting for him. In the movie, shortly after the two get married, Henry time travels and is gone for quite some time. When he returns, Claire doesn't seem excited to see him. She says her life doesn't stop just because he's gone, and she mentions how bad it feels to sit around waiting for him. In the book, Claire seems much more understanding of the fact that Henry can't help how long he is away, and her cold shoulder attitude was added in for the movie.

The Vasectomy

Henry and Claire have been struggling to carry a pregnancy to term; each time she gets pregnant, a miscarriage tragically occurs. Henry, not wanting Claire to deal with the repeated heartaches, makes the decision that he will get a vasectomy without Claire's knowledge so that no more miscarriages will happen.

In the book, he chickens out and ends up time traveling from the clinic. In the movie, this doesn't happen. Henry goes through with the procedure and time travels afterward, and he tells younger Claire that he did something she will not like. It's not until he time travels back that Claire finds out what he did.

Time Traveling Relations

Henry goes home after the almost vasectomy in the book, and he discusses it with Claire. Together, they decide that he will get the procedure done, but they make love one last time beforehand, resulting in her getting pregnant. In the movie, Claire still gets pregnant, even though he gets the vasectomy. How does that happen?

A somewhat younger Henry time travels to the future, Claire's present, and the two sleep together. Since he hadn't gotten the vasectomy yet, he is able to get her pregnant. Nine months later, baby Alba is born!

Alba's Birthday

Henry time travels forward and meets his daughter when she is ten. She tells him that he passed away when she was only five-years-old. In the movie, Alba's fifth birthday is a big deal because of this, as it signifies that Henry has less than a year to live.

This is also the day that future Alba travels back and tells present Alba that her father will die. In the book, they do not mention her fifth birthday party, and Alba had come on a different day to tell her younger self about her father's death.

Singing

Alba is known as a time-traveling prodigy because sometimes she can control her time traveling. In the movie, there is a sweet little scene where Henry tells Alba that he's been traveling a lot lately. She tells him to try to stay, and he asks her how she does it. She says, "When I feel like I'm going, I sing. I sing to myself." Henry decides that he should try it, and together they sing the first few lines of  "Daisy Bell." Unfortunately, the singing does not work, and Henry time travels anyway, leaving Alba alone in the room.

Picking Locks

Henry knows how to pick locks, and this comes in handy when he time travels. He can easily break into buildings to steal clothes or money when he needs to. The novel tells us about Henry traveling to see his younger self to teach him how to pick locks, but, in the film, we see that it is Alba who Henry teaches instead.

They practice on a door in their home with Henry explaining to her. This later gets Alba trouble when she opens a locked closet with Christmas presents inside.

Henry's Death

Henry is aware that he is going to die the year that Alba is five, but he is unsure of exactly when. He eventually figures out that he will die on New Year's Eve. In the movie, they show exactly how he found this out. He time travels to the future and ends up outside his home where there is snow on the ground and fireworks are above. He looks inside and sees himself lying on the floor dying. Time-traveling Henry presses his hand to the window before disappearing again. When he dies in the present, we can see the handprint on the window where his past self had been.

Coming Back

Henry's death is tragic and painful for Claire. He reassures her via letter that he will be back one day when she is very very old. He does not tell her that he will be back in the movie. He comes back four years after his death to see Claire and Alba. Claire asks him why he didn't tell her that he would be coming back. "I would have been right here waiting." He tells her that he doesn't want her to spend her whole life waiting, a comment that he does make in the book's letter.
