Dennison was working in the costume department at the production office of the Lakeshore-Sidney Kimmel Entertainment film "One for the Money" when paramedics were called Aug. 31. He was admitted into UPMC Mercy hospital and died two days later.

The story quoted star Katherine Heigl: "It was an honor and a privilege to work with Michael. I am heartbroken by his sudden passing as is everyone here on the film. My love and prayers go out to his family and friends. I pray they are surrounded by much love, grace and compassion during this time of grief and loss. I will never forget Michael and his wonderful, passionate, talented spirit."

Dennison received a Primetime Emmy nomination this year for his work on Lifetime telefilm "Georgia O'Keeffe." He died four days after the awards show.

In lieu of flowers, the family asks that donations be made to the Center for Organ Recovery & Education in Pittsburgh. Dennison donated five of his organs to recipients in three states, THR said.
