My Best Friend's Birthday is an unfinished 1987 amateur comedy film directed, edited, co-written, co-produced by and starring Quentin Tarantino.

In an interview with Charlie Rose (available on the Region 1 Collector's Edition DVD of Pulp Fiction), he referred to it as a "Martin and Lewis kind of thing."

[1] In 2019, a book titled My Best Friend's Birthday: The Making of a Quentin Tarantino Film, written by Andrew J. Rausch, was published by BearManor Media.

The book features interviews with all of the film's principal personnel, including Quentin Tarantino, Craig Hamann, and Roger Avary.

In actuality, some rolls of film were simply discarded by mistake, and Tarantino, unsatisfied with the final product, edited together the scenes he liked, leaving the project unfinished.
