Sandra Bullock and Keanu Reeves in The Lake HouseTHE LAKE HOUSE

In The Lake House, Sandra Bullock plays Kate Forster, a Chicago doctor living in the glass-encased home of the movie's title. Upon abandoning her domicile for a move back to the city, Kate leaves a letter for the next tenant in the edifice's mailbox; the note is received by Keanu Reeves' architect Alex Winter, who responds, thus beginning a pen-pal relationship between the two. Based on their shared tastes, histories, and a fondness for melancholic gush, it's obvious the two are Meant for Each Other. But, unfortunately, a Happily Ever After doesn't appear in the offing, as there's a major hitch to their relationship: Kate lives in 2006, while Alex is firmly nestled in 2004.
