Produced by Les Studios Tex and DIC Productions, L.P., the series was initially shown mornings on the PAX network premiering on 2 October 1999, often with infomercials bookending the program.

An ashcan comic book tie-in also titled Archie's Weird Mysteries, written by Paul Castiglia, pencilled by Bill Golliher, inked by Rick Koslowski and colored by Stephanie Coronado (née Vozzo) was published in 1999.

The first issue notably serves as an origin story for the canon's premise, showcasing the implied lab incident that turned Riverdale into supernatural central, and the moment when Archie decided to start his Weird Mystery column.

"Weird" was dropped from the title starting with #25, signaling the end of the tie-in with the television series, and the comics were canceled at #34 after ten issues of doing straight mystery stories with no supernatural or science-fiction components.

The film consists of shortened and edited versions of the episode "Attack of the Killer Spuds" and the Riverdale Vampires trilogy made to run at feature-length.
