A prize-winning

Leon Lee's 23-minute film titled "The Day To Choose" puts its main character, a lawyer and strong opponent of the death penalty, in the difficult position of choosing how to punish the murderers of his wife.

Lee, a student in the German language department at Soochow University, developed the film with his producer Cheng Kuang-yu, based on a script that Cheng had long wanted to realise.

"What I really want to discuss in this short film is not only the issue of capital punishment, but how much a human will stick to (his or her ideals) when faced with adversity," Lee told Reuters on the set of the film.

The picture will screen in the short film corner at the prestigious annual Cannes festival in France on May 11-22 and has already won "Best Drama Short Film" at the 2016 Universe Multicultural Film Festival in California last month.
