When it comes to intelligent farce, Kenji Uchida is Japan’s undisputed master so remaking his 2012 tale of love, crime, and mistaken identity Key of Life was always going to be a tall order. Thankfully it’s one Lee Gye-byeok largely manages to meet as he skilfully relocates the tale to South Korea and swaps Uchida’s complicated farce for a more lateral double sided comedy. While not as accomplished as Uchida’s hilariously intricate original, Luck-key (럭키) manages to charm with its thoroughly romantic, comically absurd, approach.
On one side of town, hitman Hyung-wook (Yu Hae-jin) finishes off his latest assignment and disappears into the night, while on another out of work actor Jae-sung (Lee Joon) contemplates suicide only to be interrupted by his landlady’s exasperated pleas for the back rent. In a fairly hopeless state, Jae-Sung heads out to the local bath house, intending to bid the world goodbye in a more dignified state. Hyung-wook also ends up at the same destination to wash the blood off his hands, only to embarrassingly slip on an errant piece of soap and knock himself out cold. Remembering admiring Hyung-wook’s expensive watch on the way in, Jae-sung makes a split second decision and switches locker keys with the unconscious rich guy.
Jae-sung decides to put his affairs in order by using Hyung-wook’s money to pay off old debts as well as experience one day as wealthy man before doing himself in. When Jae-sung discovers Hyung-wook has lost his memory and assumed Jae-sung’s identity, he decides against giving back Hyung-wook’s belongings in favour of trying on life in the fast stream. Jae-sung has also grown attached to a young woman who inexplicably appears on Hyung-wook’s TV, though he does wonder why Hyung-wook has all of these weapons and telephones, not to mention a big board of investigation material, stored away in a hidden room…
Each man begins to live a different life thanks to assuming the contents of the wrong locker. Hyung-wook has the rawer deal as he can’t remember anything about himself and ends up at Jae-sung’s apartment to find it covered in old food cartons and beer cans with his hangman’s noose still lying in the middle of the floor. With only two bucks in his wallet and no cards, he even has to ask the paramedic who brought him in, Lina (Jo Yoon-hee), to lend him the medical fees. Somewhat improbably Jae-sung’s identity card tells him that he is 32 years old (coincidentally the same as Lina) which can only make one think that he must have had a very hard life. Nevertheless, Lina decides to help him by taking him home and getting him a job in her mother’s restaurant.
Even though he can’t remember who he was before, Hyung-wook gradually reveals a different side to himself as Jae-sung, enjoying being a part of Lina’s busy family life. Jae-sung, by contrast, moves further towards the shadows as he becomes increasingly determined to protected the woman on Hyung-wook’s TV screen who turns out to be a whistleblower in a high profile fraud case. Eun-ju (Lim Ji-yeon) is a woman afraid for her life who leaves her apartment as little as possible, but eventually Jae-sung tracks her down and begins to woo her in impressively romantic ways, only to discover he’s made everything worse by misunderstanding the nature of the situation she finds herself in.
Experiencing a different sort of life highlights for each of the men what was making them so unhappy – Hyung-wook realises the value of a warm and supportive family life whilst Jae-sung finds purpose and drive in his desire to protect Eun-ju. Both men had, in a sense been “acting” as a part of their daily lives, living a kind of half life which frustrated their attempts to move forward. Through living in someone else’s world, these hidden parts of themselves – Hyung-wook’s softer, more feminine side, and Jae-sung’s masculine desire to charge of his life, become “unlocked” and allow them to become the people they always meant to be all along.
Dispensing with Uchida’s farce structure, Lee Gye-byeok more or less eliminates the third major character from the original script in order to more neatly split the action between the two guys who then mirror each other as they each begin to move more towards the centre whilst also making tentative moves towards romance. Filled with gentle, often absurd humour and taking pot shots at everything from gangster clichés to diva TV stars, Luck-key makes all the right moves in its relocation to Korea, bringing both amusing comedy and genuine romantic warmth with it.
