 * Shout-Out: The movie Mrs. Page watches on TV early on in the film is actually John Hughes' next film She's Having a Baby


 * Troubled Production: The experience of making the film was not a happy one for John Hughes as many shooting days would either be lost or delayed due to weather issues or having to work around certain loopholes (for example, a sequence involving a train had change shooting locations due to a lack of snow and the crew had to create a train route from scratch as the local train company wouldn't allow them to use theirs). Also, the rough cut ran over three hours and the film spent many months in post-production so to cut the film to a manageable length (this is also why references to Hughes's next film appear, as it has begun production right after this film finished filming). In addition to these problems, Hughes was also smarting over the fact that his long term business relationship with Molly Ringwald had gone sour after she turned down the Lea Thompson role of Amanda Jones in Some Kind of Wonderful. Hughes was so upset over the rejection that he never worked with Ringwald again for the rest of his life.
