Shailene Woodley and Ansel Elgort are names that you may have heard of if you keep up with pop culture. Before enlisting in big projects like Big Little Lies and Baby Driver, the two actors portrayed two teenagers who meet in a cancer patient support group and quickly bond. Their friendship turns into love and even takes them to Amsterdam as they track down an author. It's a sweet and poignant film with an ending that's guaranteed to have you bawling hard.
