Robert Stack worked as host of Unsolved Mysteries from 1987 – 2002, guiding viewers through all kinds of cases that were never satisfactorily resolved.
The show came to an end in 2002, but it was rebooted in 2008 for Spike with Dennis Farina as host.
The FilmRise release will be the first time that updated versions of the Robert Stack episodes can be streamed online, according to The Wrap.
Both seasons of the Spike reboot with Dennis Farina are currently available streaming on Amazon.
