CineVegas has finalized the complete lineup for its 11th annual festival, including Bobcat Goldthwait‘s World’s Greatest Dad as the closing night film, it was announced today by Artistic Director Trevor Groth. Starring Robin Williams, the dark comedy centers around high school poetry teacher Lance Clayton, who, after a freak accident, desperately tries to reconnect with his teenage son Kyle (Daryl Sabara), as well as a painfully adorable art teacher, Claire (Alexie Gilmore). Presumably, dogs are not fellated. For more information on the festival, which runs June 10-15 at the Palms Casino Resort and Brenden Theatres in Las Vegas, click here.
