Chasing Amy (1997)

Visible crew/equipment: The cameraman is visible in the reflection of window while Holden is walking back to his car in the rain.

[After Banky pulls out a stack of porno magazines from his bag.]
Holden McNeil: Oh my God. Who are you, Larry fucking Flynt? What are you going to do with all of those?
Banky Edwards: Read the articles. What do you think I'm going to do with them? They're stroke books, stupid!
Holden McNeil: You've got like, thirty books there! We're only going to be gone for two days!
Banky Edwards: Variety's the spice of life. I like a wide selection. Sometimes I'm in the mood for nasty close-ups, sometimes I like them arty and air-brushed. Sometimes it's a spread brown-eye kind of night, sometimes it's girl-on-girl time. Sometimes a steamy letter will do it, sometimes - not often, but sometimes - I like the idea of a chick with a horse.

Trivia: During the lesbian bar scene, they are all around the table. The lights behind them glow eerily like portholes. They re-enact the scene from "Jaws" where they compare injuries, only with cunnilingus stories. Even putting the leg on the table comes from "Jaws." This scene was originally meant to be in Mallrats, but was rejected by the studio.

Question: Holden tells a fan that he likes to think of Bluntman and Chronic as Rosencrantz and Guildenstern meet Vladamir and Estragon. I know who Rosencrantz and Guildenstern are, but who are Vladamir and Estragon?
