It's been almost three years since the movie adaptation of the book The Fault in Our Stars premiered in theaters around the country. Fans not only fell in love with the story as a whole but the characters as well.

Today, in honor Ansel Elgort's birthday, the editors here at J-14 decided to dive into the actors' lives who played these timeless characters. What have they been up to? Where have they been? Have some completely gone under the radar? Not only have these actors moved on to other roles, but they have also changed a lot over the past few years as well.

We've highlighted the change in their looks as well as what they are currently doing in their professional life and anything significant that is going on in their personal lives.
