Continuity: The amount eaten from the apple between shots When Johnny is in the playroom with the bitten apple in his hand.
Continuity: Near the end of the movie, Johnny has being announced and is coming up the stairs and Neddie is trying to persuade Linda not to give up. As Neddie then walks away, he has his right arm fully extended down, forgetting that he is supposed to be carrying a drink, then, a second later, he remembers it and bends his right elbow at 90 degrees, keeping it bent.
Incorrectly regarded as goofs: At the start of the movie, Johnny goes to the Seton mansion and meets the family. Linda wants to plan the party announcing the engagement and tells him, "This Saturday is New Year's Eve." We know this scene takes place on a Sunday, because the family has just returned from church. That would make the date Chistmas day. There are no visual indications that it is Christmas, or even the Christmas season, but the church congregation sings the Christmas hymn "Hark! The Herald Angels Sing," which is used exclusively during the Christmas season, often only as the closing hymn on Christmas Day.
