Four set to begin 'Endings'

Dennis Hopper, Scott Caan among those newly cast

Dennis Hopper, Scott Caan, Tricia Helfer and J.K. Simmons are boarding "A Beginner's Guide to Endings," a dark comedy written and directed by newcomer Jonathan Sobol.

Nicholas Tabarrok, whose "Defendor" was one of the few films sold during the Toronto International Film Festival, is producing through his Darius Films banner.

"Endings" centers on three brothers who, upon learning they only have a few days left to live, set off to reverse a lifetime of mistakes.

Hopper and Simmons are playing the brothers' father and uncle, respectively, while Caan is one of the brothers. Helfer is Caan's girlfriend, a woman with a dangerous past.

Shooting is due to start the last week of October in Niagara Falls, N.Y. Sobol hails from the region, and "Endings" is something of an homage to his hometown.

Tabarrok is about to start production on "Welcome Back Satan," a comedy written and directed by Sara Lohman.

Hopper, repped by the Collective, stars in Starz's "Crash" series.

Paradigm-repped Caan recently appeared on "Entourage," while Helfer, repped by Paradigm and Gilbertson Management, is best known for her work in "Battlestar Galactica." Simmons, repped by Gersh, can be seen in Mike Judge's "Extract."
