2015—present: Big screen debut

In early 2016, Minho extended his popularity as an actor. He was cast in several projects, including a new historical Korean drama entitled Hwarang: The Poet Warrior Youth, to be aired on December 19, 2016 on KBS2. His debut movie project titled Canola, alongside Youn Yuh-jung and Kim Go-eun and directed by Yoon Hong-seung (pseudonym Director Changwhich), was filmed in 2015 and was released on the big screen May 2016.[31][32] The second one is a supporting role in a film entitled Marital Harmony, to be led by Lee Seung-gi and Shim Eun-kyung. The movie is the second installment in a planned trilogy by Jupiter Films after the 2013 box-office hit The Face Reader.[33][34] Minho was also featured in the music video for Romeo's third mini album. This was possible thanks to Minho's connection to Hwang Sung Wook, the CEO of Romeo’s agency CT Entertainment. The CEO worked as a manager for SM Entertainment for more than 10 years, spending part of that time as a manager for Minho's group Shinee.[35] Choi is set to appear in the movie DERAILED (a.k.a. NO WAY TO GO) alongside veteran actor Ma Dong-seok. The movie is directed by Lee Seong-tae and premiered at 2016 Cannes Film Festival.[36][37] The movie will have its world premiere screening at the 21st Busan International Film Festival in October.[38]
