You can see Prince in the hotel room scene,where he brings a suitcase filled with guns to Robert Deniro.
But the scene from Pulp Fiction is only verbally told by Prince in the short film “American Boy”.It’s a movie where he tells stories from his life as a road manager,drug addict and actor.
I don’t have the Dvd of Taxi Driver myself,only the Criterion laserdisc.
The Laserdisc does have a fascinating commentary track by Scorsese and Paul Schrader though.
