Contrary to popular belief, It’s a Mystery was not the first time Neil Buchanan and Tim Edmunds worked on a project with Sophie Aldred. Way back in March 1991, Sophie appeared as a guest on the live Saturday morning TVS show Motormouth (which was presented by Neil and produced by Tim). The show was recorded live at the Maidstone Studios, presumably the same studio WOW! would later be filmed in.
Sophie appeared in many many children’s programmes during the late 1980s and 1990s – mainly for BBC including Corners, Words and Pictures, Dilly, Numbertime, Melvin and Maureen’s Music-a-Grams, Corners, Tiny & Company/Living UK, Search out Space, The Children’s Channel etc before switching between both BBC and ITV for the aforementioned programmes alongside It’s a Mystery, WOW! and Zzzap!
The decision to include Sophie Aldred in the show as Minnie the Mini Magician was probably the joint decision of Buchanan, Edmunds and Driana Jones. This was likely one of the last major decisions taken by Buchanan and Edmunds. Driana decided to revamp the look of the show (the first time in 5 years) as it was admittedly starting to look a bit stale and reflected the new character/ elements.
