Posthumous is a word to describe something which occurred after the death of the originator.  Here's a few (in detail) to begin ...


Heath Ledger:  Actor, perhaps best known for his role as "The Joker" in the 2008 film The Dark Knight for which he won an Academy Award for said performance.  The film was released after his death in 2008 and he remains one of only 2 actors to receive an Academy Award posthumously (the other was Peter Finch for the 1976 film Network)

Larry Breeding:  Actor, best known for his starring roles in the short-lived 70s sitcoms Who's Watching the Kids and The Last Resort.  In 1982, he was set to star in a new ABC sitcom called It's Not Easy when he died in a freeway collision in Hollywood.  The last thing he filmed was an episode of Laverne and Shirley titled "The Fashion Show" which aired in February of 1983, 5 months after his death.  The episode was not in memorial to him

Diana Hyland:  Actress, who appeared as Joan Bradford in the sitcom Eight is Enough.  During the show's first season in March of 1977, she passed away after filming just 4 episodes (2 of which aired before her death).  For the remainder of the season, the character's disappearance was never mentioned, yet in Season 2, it was mentioned that Tom Bradford was a widower.  At the 1977 Emmy Awards, she won for Best Supporting Actress in a Comedy or Drama Special for The Boy in the Plastic Bubble, a TV movie she filmed in 1976.  Her lover at the time, John Travolta, accepted the award on her behalf

Heather O'Rourke:  Child Actress, best known as Carol Anne in the Poltergeist trilogy.  She passed away in 1988 before filming of Poltergeist III was complete, so a stunt double was used in the final scene, which is why you do not see her face at the end

Bruce Lee: Martial Artist/Actor...Bruce Lee died during the filming of The Game Of Death. It was decided to rework
                the movie and change the plot. Only about 11 minutes of original footage with  Bruce Lee was used in
                the new movie called Game Of Death. The new plot called for actors Yuen Biao and Tai Chung Kim to
                spend most of the time in disguises, hiding the fact that they looked nothing like Bruce Lee. Most of the
                fight scenes were stock footage of Lee from his previous movies and exhibitions. The movie was released
                in 1978, five years after his death.
