Planes, Trains & Automobiles

On instruction from John Hughes, Edie McClurg's role as the St. Louis rental car agent was partially improvised. Hughes told her to simply riff a fake phone conversation with someone about Thanksgiving plans while Steve Martin remains waiting in line staring at her to finish up. McClurg came up with the idea to speak with her sister about who was going to make what adding "You know I can't cook!" Hughes asked her how she came up with those lines so quickly and she replied that, like his scripts, she just drew it from her own life. McClurg claims to this day that random people ask her to tell them they're fucked.

On the bus the child running up and down the aisle accidentally conks the woman sitting in the front seat hard on top of her head with the handle of the toy he is playing with. Watch her eyes to see both how startled she was and also, to her credit, how determined she was not to let it show.

After all the end credits, there's a shot of advertising executive William Windom in the office as in the scene in the beginning of the movie, still examining the pictures Neal Page was waiting for him to finish perusing at the staff meeting.

The theatrical and VHS releases have the closing Paramount logo after the post-credits scene. On further releases including the DVD, the logo is edited out, and the movie ends immediately.
