Bad Day to Go Fishing (original title, Mal día para pescar) is a Spanish-Uruguayan film directed by Álvaro Brechner and released in 2009.

The screenplay was written by Álvaro Brechner in collaboration with Gary Piquer, and was adapted from a short story by the Uruguayan writer Juan Carlos Onetti.

Jacob van Oppen, an East German who is the former strongest man on earth, and his manager Orsini, a scrawny yet dapper businessman who calls himself "the Prince," makes a good living by travelling around small South American towns and organizing wrestling exhibitions in run-down theaters.

Once this oddball pair disembark at the village of Santa Maria (in an unspecified country), business really kicks off: the local newspaper is immediately gung-ho on sponsoring the fight, helping hands placard posters announcing the big event and putting an open call for a worthy adversary.

Although the cunning editor of the local newspaper is convinced to have sniffed out Orsini's secret, he very well might be on a false track... Bad Day to Go Fishing premiered at the Critic's Week of the 2009 Cannes Film Festival.
