Fan Casting The Wayans The Munsters (2006)

Back in 2004, none other than Shawn, Marlon, and Keenen Ivory Wayans — of Scary Movie and White Chicks fame — were attached to write and produce a Munsters movie reboot, which would've transplanted the classic characters to a modern-day setting. Surprisingly, Shawn and Marlon weren't set to appear in the cast, although tentative plans were in place for Keenen Ivory to direct. It's unclear why this version didn't get off the ground, as no further updates ever surfaced.
