Bloody Birthday is a 1981 American slasher film directed by Ed Hunt, produced by Gerald T. Olson,[1] and starring Susan Strasberg, José Ferrer, and Lori Lethin.

Its plot follows a group of three children born on the same day during a solar eclipse who begin committing murders on their tenth birthdays.

Sheriff Brody shows the class a jump rope handle that was found at the scene of yesterday's crime, but fails to obtain any new information about the murders and leaves.

At the kids' birthday party on June 9, Curtis tricks Joyce into believing that he poisoned the cake to make her look crazy to everyone.

That night, Debbie murders Beverly and gets Curtis and Steven to help her move the body away from the house in order to avert suspicion.

Bloody Birthday was given a belated limited release theatrically in the United States by Rearguard Productions in 1981.

Bloody Birthday received mixed-to-negative reviews from critics, but the performances (particularly those of Jayne, Freeman, and Hoy) were praised.
