I have always loved this home, and you can read all about it at Hooked on Houses... Julia explains that it was actually just the driveway and backyard from this home that were used in the movie. (She also wrote about this house when it was for sale in 2011.) The front exterior belonged to a different house in Pasadena. You can read more about it here.

According to Zillow, there is already a contract pending on the Alhambra home, but you can still click over and take a sneak peek... And if you loved this movie as much as I did, you will want to see Hooked on Houses' thorough analysis of the two homes here and here. Enjoy!
