LOS ANGELES (Hollywood Reporter) - "ER" star Linda Cardellini is set to join Paul Walker in "Heaven Project," an indie supernatural mystery shooting in Winnipeg, Manitoba.

The story follows an ex-con who is sentenced to death and wakes up from his lethal injection in a small Oregon town. Working as a groundskeeper for a mental hospital, he is told he was given a second chance by God but questions whether he ever really died.

Cardellini will play the hospital's administrator and Walker's love interest.

She played Velma in the "Scooby-Doo" movies and will appear in CBS' Larry McMurtry miniseries "Comanche Moon." Walker was in theaters last year with "Flags of Our Fathers."
