Initially published by Foldes Press, Super Thriller was a British comic deliberately designed to ape the look of American comics imports. From #6 it featured superhero Ace Hart, the Atom Man, with back up strips including Dirk Daring, Steve Callahan (a western hero) and Tess Moran. After a few issues World Distributors bought the title from Foldes, and continued to publish it to #34, after which it was retitled Western Super Thriller, to cash in to a growing interest in Westerns. It would survive up to #82 under this new title. World Distributors also released three Super Thriller Annuals towards the end of the 1950s, all starring Ace Hart.
Atlas Comics in Australia also published Super Thriller Comics with Ace Hart as the lead, reprinting the UK title.
