As summer is approaching and the temperatures are rising, it's not like we need any excuses to go outside and lie barefoot in the grass. And what better companion for our sun-drenched reveries than a good book?

For those who are always tempted to go see adaptations of books once they're in theaters, here are 20 upcoming movies based on books — which means 20 books to read before the movie versions come out and spoilers start roaming the internet. You haven't got much time to catch up on the first one, but the rest of them should be enough to keep you company for the summer. And if you've read them already, these upcoming movies based on books are all promising projects to look forward to.

1. Alice Through The Looking Glass — May 27

Mia Wasikowska, Johnny Depp, Helena Bonham Carter and Anne Hathaway return for this sequel to Alice in Wonderland, joined by Sacha Baron Cohen as the enigmatic Time. With visuals that are as stunning as always, the second movie sees the Mad Hatter in trouble. Will Alice be able to save him?

2. Me Before You — June 3

Of all the upcoming movies based on books in this list, this one might be one of the most highly expected. Based on the novel by Jojo Moyes, Me Before You stars Game of Thrones' Emilia Clarke as Louisa, a young assistant to the paralyzed Will (Sam Claflin). Judging from the trailer, the movie stays true to the emotional power of the original story. The two co-stars also had exceptional chemistry, which The Hunger Games' Claflin showed in a series of pictures of the set he posted on his Instagram. It'll be the perfect movie to start the summer.

3. Genius — June 10

Based on A. Scott Berg's Max Perkins: Editor of Genius, this movie stars Jude Law and Colin Firth respectively as the American novelist Thomas Wolfe and Max Perkins, the editor who discovered Ernest Hemingway and F. Scott Fitzgerald. The story centers on the conflicted relationship between the artist and the businessman, and it looks like we've got stellar performances to look forward to.

4. The BFG — July 1

A children's classic, Roald Dahl's The BFG tells the tale of Sophie, a young orphan girl who befriends a Big Friendly Giant, played by Oscar-winner Mark Rylance. Directed by Steven Spielberg, the fourth one of the upcoming movies based on books also stars Bill Hader as Bloodbottler, a not-so-friendly child-eating giant.

5. Nerve — July 27

Originally a book by Jeanne Ryan, Nerve stars Emma Roberts as a high school senior playing a dangerous game of online truth or dare with a character played by Dave Franco. She's reticent at first, but she starts to have fun... until the game escalates very quickly.

6. The Light Between Oceans — September 2

Of all the upcoming movies based on books, The Light Between Oceans is the one bound to break our hearts. The story follows a couple, played by Michael Fassbender and Alicia Vikander, who save a young baby from a stranded boat. Years later, they are faced with a profound dilemma when they seem to find the child's real mother.

7. Queen Of Katwe — September 23

The novel by Tim Crothers is the true story of Phiona Mutesi, a Ugandan teen who becomes one of the world's best chess players. Lupita Nyong'o is playing the young girl's mother, while newcomer Madina Nalwanga stars as Phiona. In classic Disney fashion, it's a universal story about chasing your dreams. Isn't the trailer touching?

8. Miss Peregrine's Home For Peculiar Children — September 30

Directed by Tim Burton and starring Eva Green, the adaptation of Ransom Riggs' book about Jacob and his discovery of a hidden house for children with special powers will make for one hell of an adventure. The orphanage is there to protect these children from evil creatures, and run by a headmistress called Miss Peregrine, who might remind you of a darker Mary Poppins.

9. The Girl On The Train — October 7

Emily Blunt stars as the main character Rachel, alongside Justin Theroux and Luke Evans, in this adaptation of the book by Paula Hawkins. Rachel is an alcoholic and a recent divorcee who becomes obsessed with a couple she sees on her daily commute — and gets involved in a murky crime story. The first trailer dropped on April 21, and it's chilling.

10. A Monster Calls — October 14

With a cast including Felicity Jones, Liam Neeson and Sigourney Weaver, the adaptation of Patrick Ness's novel follows a young boy who escapes his dreary life by imagining a fantasy world.

11. Inferno — October 28

Tom Hanks will return as Robert Langdon, the hero of Dan Brown's The Da Vinci Code, in this new international scavenger hunt Inferno. The sequel to Angels & Demons, Inferno was at the top of the New York Times best-seller list in 2013.

The big-screen adaptation of Shûsaku Endô's novel is reportedly a passion project for director Martin Scorsese, who's been waiting to make it for several years. Starring Andrew Garfield, Adam Driver and Liam Neeson, Silence is about the struggle of two 17th-century Jesuit priests who travel to Japan to find their mentor and spread Christianity, but are instead faced with violent persecution. The movie could premiere at the Cannes Film Festival in May, but it hasn't been assigned an official release date.

13. Billy Lynn's Long Halftime Walk — November 11

Ben Fountain's novel, which won the National Books Critics Circle Award for Fiction in 2013, will be brought to life by Ang Lee, with a stellar cast including Kristen Stewart, Garrett Hedlund, Steve Martin, Vin Diesel and Chris Tucker. In his first big role, Joe Alwyn will star as Billy, the 19-year-old who survives the Iraq War.

14. Fantastic Beasts And Where To Find Them — November 18

Since the Harry Potter movies have come to an end, fans are all looking forward to Eddie Redmayne as Newt Scamander. In this story by J.K. Rowling, he's the author of what will later become Harry Potter's textbook. And as the title reveals, we'll get to see a whole lot of fantastic and unknown creatures on screen.

That's all for the upcoming movies based on books to be released in 2016, but there's also a few still unplanned projects to come.

15. The Circle — TBD

Among the upcoming movies based on books, The Circle is one that has been highly praised. A satire of the tech industry, the movie adaptation will star Emma Watson in the role of a young woman who lands a job at a powerful tech company called the Circle. She'll be joined by Tom Hanks and John Boyega.

16. The Zookeeper's Wife — December, 2016

Based on the book by Diane Ackerman, The Zookeeper's Wife will star Jessica Chastain and Daniel Brühl — Baron Zemo in Captain America: Civil War — in the true story of the Warsaw Zoo, whose keepers saved hundreds of people during World War II. While there's no trailer out yet, photos of the set have already surfaced.

17. The Lost City Of Z — TBD

The Lost City of Z is the true story of British explorer Percy Fawcett, who went searching for an ancient civilization in the Amazon in 1925, but never returned. The adaptation stars the new Spider-Man, Tom Holland, as well as Charlie Hunnam, Sienna Miller and Robert Pattinson, so it's setting high standards for other upcoming movies based on books.

18. November Criminals — TBD

Sam Munson's book follows a high schooler who decides to investigate the death of a fellow classmate. Ansel Elgort and Chloë Grace Moretz will bring the story to the big screen.

19. Let It Snow — November 22, 2017

There's no such thing as too many John Green adaptations in our lists of upcoming movies based on books, and this set of three short stories set during the festive season proves it. With the cast yet to be confirmed, the movie's release was pushed back by almost an entire year, to Thanksgiving 2017.

20. The Chronicles of Narnia: The Silver Chair — TBD

Yes, the Narnia movies are returning with more upcoming movies based on books, namely an adaptation of the fourth book — but no, they will not constitute a sequel to the existing trilogy, meaning the original cast won't return.

Back in January, producer Mark Gordon told Collider about the progress of the project:

"We’re hoping to be able to make the movie very shortly. We’re very excited about it."

He also specified that this would be a new take on the Narnia books:

"It’s all going to be a brand new franchise. All original. All original characters, different directors, and an entire new team that this is coming from."

Hopefully this list of upcoming movies based on books should be long enough to fuel your late-night reading sessions for a while, but will you able to have read them all before the movies come out?
