The Lake House is a romantic drama film remake of the Korean motion picture Il Mare (2000). It was written by David Auburn and directed by Alejandro Agresti and stars Keanu Reeves and Sandra Bullock as Alex Wyler and Kate Forester, an architect and doctor living in 2004 and 2006 respectively. It was released to Filipino theatres on June 14, 2006 and North American theatres on June 16, 2006.

The movie centers around lonely Dr. Kate Forster (Sandra Bullock) who, on a winter morning in 2006, reluctantly leaves the beautiful lake house where she has been living for a job in a Chicago hospital. On her way to Chicago, she leaves a note for the lake house's new tenant asking him to kindly forward her mail and telling him about the paw prints by the front door and the box in the attic.

However, Alex Wyler (Keanu Reeves), the new tenant, sees a different lake house, one which was neglected, dirty, and there were certainly no paw prints. He disregards Kate's letter until a few days later; he is painting the jetty and a stray dog runs across the fresh paint leaving paw prints where Kate said they would be. He writes back to Kate, only to discover that they are separated in time by two years, with Alex living in 2004 and Kate living in 2006.

As Kate and Alex continue to correspond through the mailbox, they find themselves falling in love. Because Kate is in the future, she can tell Alex where to look for her in 2004 in places she has been. In one occasion, she asks Alex to bring her back something important (a gift for her father; her favorite novel), which she left two years ago during a train station meeting with her then-beau. Alex goes to the station and finds the item and sees Kate with long hair. Even though he has the item, he does not place it in the mailbox to return it to her. Instead, he says that he will return it to her personally, "one way or the other."

By the same dog that put prints on the jetty, Alex meets Kate's boyfriend Morgan and is invited to attend her birthday party. At the party, Kate is frustrated with Morgan's sincere but smothering ways. She wanders outside, where Alex is sitting, attempting to determine how to let this earlier version of Kate know that her "letter paramour" is here in person. Kate does not know who Alex is, as their relationship is in her future. However, the two share a dance and a romantic moment, but it is interrupted by Morgan.

Determined to bridge the distance between them at last and unravel the mystery behind their extraordinary connection, they tempt fate by arranging to meet. After a failed attempt at a date meeting at Il Mare, a fancy restaurant, in 2006, Kate retreats, believing she will never have happiness. She urges Alex to move on.

A 2006 incident at Daley Plaza in downtown Chicago becomes a crucial moment in the efforts of the two erstwhile lovers to meet.

According to the website Rotten Tomatoes, 2/3 of the critics gave the movie a negative review,. Many critics point to the movie's flawed internal logic, particularly the time paradox created by the ending. USA Today critic Claudia Puig wrote, "The Lake House is one of the more befuddling movies of recent years. The premise makes no sense, no matter how you turn it around in your head." Roger Ebert, while pointing out the movies logical inconsistencies, wrote, "Never mind, I tell you, never mind!" Ebert gave it a positive review, 3 1/2 stars of four, noting, "What I respond to in the movie is its fundamental romantic impulse."
