Quackser Fortune Has a Cousin in the Bronx is a 1970 comedy film directed by Waris Hussein, written by Gabriel Walsh, and starring Gene Wilder and Margot Kidder. It focuses on a poor Irish manure collector (Wilder) who falls in love with an American exchange student (Kidder) after she almost runs him over.

Quackser Fortune earns a living in Dublin by collecting horse manure and selling it to locals for garden fertilizer. Quackser has an affair with Betsy Bourke, a housewife who is one of his customers.

One day, Quackser is almost run over by Zazel Pierce, a wealthy American exchange student from Connecticut studying abroad at Trinity College. Quackser takes an immediate liking to Zazel, who helps educate him on Irish history. Zazel invites Quackser to a dress ball held by the college, but upon his arrival, she opts to ignore him, instead associating with her sophisticated classmates. The students' taunting of Quackser results in a fight, during which he escapes with Zazel. The two spent the night at an upscale hotel, where the two have sex before she leaves him for the night.

The following day, Quackser attempts to confront Zazel at her dormitory on the college campus, only to learn she has moved out. He is further dismayed upon learning of a new city ordinance banning horses on the streets of Dublin, which threatens his livelihood collecting and delivering horse manure. In retaliation, Quackser releases his horses into the city streets in order to prevent them from being taken to a slaughterhouse and used as animal glue.

A dejected Quackser spends the evening binge drinking, but his spirits are lifted when he learns that a distant cousin of his who lives in the Bronx, New York City, has died and left him over £200. Upon receiving the money, he uses it to purchase a bus, and begins a new business enterprise giving historical tours of Dublin to tourists.
