In Die Hard with a Vengeance, John McClane (portrayed by Bruce Willis) quotes a line from the song Flowers on the wall by the Statler Brothers while speaking to Zeus Carver (portrayed by Samuel L. Jackson)
Zeus Carver: What am I doing?
John McClane: Cheer up. It could be worse. I was working on a nice fat suspension. Smoking cigarettes and watching Captain Kangaroo.
In Pulp Fiction, Butch Coolidge (portrayed by Bruce Willis) is singing along to Flowers on the Wall by the Statler Brothers giving emphasis to the line:
Smoking cigarettes and watching Captain Kangaroo
Bruce Willis and Samuel L. Jackson both starred in Pulp Fiction a year prior to starring together in Die Hard with a Vengeance.
Is there any evidence that filmmakers added this line in the film as a reference to Pulp Fiction? Was this line improvised by Bruce Willis?
