He will be succeeded by 'The Real O’Neals' star Noah Galvin and 'Hello, Dolly!' actor Taylor Trensch.

Ben Platt will soon be waving through a window at Dear Evan Hansen.

The actor — who won this year's best lead actor in a musical Tony Award for playing the eponymous adolescent outcast who gets caught up in an unintended lie — will exit the hit Broadway musical Nov. 19, The Hollywood Reporter has confirmed.

Platt will be succeeded by Noah Galvin, the star of ABC’s The Real O’Neals, from Nov. 21 through mid-January. Taylor Trensch, currently starring on Broadway in Hello, Dolly!, will then take on the lead role for an open-ended run.

"2 readings, 2 workshops, 3 productions and almost 4 years- hard to fathom that's it's nearly time to say goodbye to Evan and my DEH family," Platt tweeted Tuesday. Upon seeing fans' responses online, he added, "All these #Fansens out here making me cry."

It is standard practice for an actor of an original cast to depart a production after a year or less, and Dear Evan Hansen's Broadway run began previews on Nov. 14, 2016. Even more so, Platt (who is the son of producer Marc Platt) has been with the production since its origins and starred in its pre-Broadway productions in Washington, D.C., and off-Broadway. His upcoming projects include the film Drunk Parents, starring Tina Fey and Alec Baldwin, and a guest-starring role on the Oct. 5 episode of NBC's Will & Grace revival.

Dear Evan Hansen features a book by Steven Levenson, music and lyrics by Benj Pasek and Justin Paul and direction by Michael Greif. Its cast also includes Laura Dreyfuss, Rachel Bay Jones and Mike Faist. The musical opened to strong reviews in December at the Music Box Theatre, where it has since been playing to standing-room-only crowds. The Broadway run recouped its investment last month, and Platt won one of the show's six Tony Awards, which also included best musical.

Platt is repped by CAA and One Entertainment.
