This article or section refers to "enhanced version" content in the Xbox One, PlayStation 4, and PC renditions of Grand Theft Auto V and/or Grand Theft Auto Online, that is absent on the Xbox 360 or PlayStation 3 versions.
For a complete list of the features of the "enhanced" version of Grand Theft Auto V, please see here.
For other characters with the same name, see Isaac.

Isaac is a deceased character in Grand Theft Auto V, who is featured exclusively in the enhanced version.


Isaac is an actor who worked for Fred's Pictures. Fred Quincy, the founder of the film studio, wanted Isaac to produce a cartoon film called "Bip the Dog", while Isaac wanted to make a live-action film with Abe Schwartzman for a different studio. Because of this, Quincy killed Isaac and hid his body in an abandoned mine in Great Chaparral, sometime before or during 1949.


Discovering Isaac's body unlocks the vintage filters, as he is the final part of the Murder Mystery, and finding his corpse while doing the mystery will unlock the filters and add his contact to the protagonists' phones. Calling him or visiting his corpse will allow the player to change the filters whenever they wish.



  • Even though Isaac was killed in 1949, he has barely decomposed, though he is severely dehydrated. Since decomposition usually takes between three and nine months, Isaac should be little more than a skeleton. If his corpse is shot at, it will bleed.
    • This is because Isaac is actually a pedestrian model who is scripted to lay immediately dead on the ground. This is the same for the body found underwater at the earlier part of the murder mystery, as well as Brad's corpse during the mission Bury the Hatchet.
  • The film reel next to Isaac's corpse is labelled Richards Majestic, this may just be a reused prop from Legal Trouble.
