A special to celebrate the 35th anniversary of the true crime television series Unsolved Mysteries will be screened at Alamo Drafthouse theaters nationwide on October 4th. The special, called Unsolved Mysteries: Behind the Legacy, will feature fan-favorite moments and never-before-seen outtakes from the show’s multi-season run.

Co-creators Terry Dunn Meurer and John Cosgrove, along with actors, producers, and directors involved in the series, will discuss the making of Unsolved Mysteries, from audience involvement on tips, research, casting, and solving mysteries. Fans attending the Alamo Drafthouse screenings will experience a 90-minute presentation featuring the 60-minute TV special alongside a half-hour compilation of fan-favorite moments. The streaming program will only feature the 60-minute special.

FilmRise’s Sal Scamardo said, “In addition to celebrating the 35th anniversary by co-producing this new video tribute, we wanted to honor the fans who have played such an integral role in the success of the series both as fiercely dedicated viewers and as case solvers with their call-in tips.”

Alamo Drafthouse’s John Smith added, “I’m one of the many, many millennials whose Wednesday evenings were spent absorbed in Unsolved Mysteries, and who, in the present day, have been able to binge these classic episodes thanks to FilmRise. That’s why the opportunity to screen the anniversary special with fellow Stack-olytes at Alamo Drafthouse is truly exciting.”

Unsolved Mysteries: Behind the Legacy will also be streaming for free on AVOD in the United States on October 5th.
