Actor and singer Lee Seung Gi has revealed his shocking transformation in preparation for the movie "Big Family."

Lee, wearing the traditional robes of a monk, appears deep in thought as he stands before the sky with his hands under his chin.

There are other photos, too, with playfulness from Lee, wearing sunglasses and his head shaved with fans in laughter mode.

The coming-of-age movie "Big Family," directed by Yang Woo-Seok, revolves around Pyeong Man-ok, a dumpling restaurant owner whose life is turned upside down when his son (played by Lee) renounces his ties with his family to live as a monk.

The film explores themes of family and connection, highlighting the bond between Pyeong and his grandchildren, whom he has never met.

The film is set to premiere on December 11, and anticipation is building among fans eager to see Lee's portrayal of the complex character.
