On a movie concerned about special dates (since Amy Adams character wants to propose to her fiancé on February 29) comes the coincidence that both actors who play Amy's love interests in the film Adam Scott and Matthew Goode were born on April 3.
Anna calls Jeremy (in Dublin) from the B&B at approximately 8:30am on a Sunday morning. He tells her that he just got off the phone after learning that the apartment was theirs. With a 5 hour time difference it is highly unlikely that the deal was closed in Boston at 3:00 am - on a Sunday, no less.
Declan: Dublin, huh? Let me tell you something about Dublin. Dublin is a city of chances and cheats and back stabbing snakes. It is a city where the worst of humanity collects the poison of their country. I wouldn't advise you to go there.
No. Leap Year is based on a screenplay written by British screenwriter Simon Beaufoy and American screenwriters Herry Elfont and Deborah Kaplan.
How does the movie end?
After seeing Anna to Dublin, Declan returns to Dingle, and Anna returns to Boston with Jeremy. Declan holds a big Save the Caragh Pub party and makes enough money to prevent foreclosure. Anna and Jeremy move into their dream apartment at the Davenport. During their housewarming party, Jeremy admits to Anna that the reason he asked her to marry him was because the apartment selection committee required them to be married. When a fire alarm suddenly goes off and Jeremy rushes around saving his electronic equipment, Anna sees his true side and flies back to Ireland. She returnns to the Caragh and asks Declan if he would consider "not making plans" with her. Declan leaves her standing, and Anna takes that as an Irish no. They meet again on the cliffs where Declan explains that the reason he left her standing was to get his mother's claddagh ring in order to propose marriage to her. In the final scene, they are touring the country as newlyweds in Declan's classic Renault 4.
