The design of the caterpillar-like creature in The Monster That Challenged the World is on my shortlist of favorite monsters of the 1950s. Although the script resorts to the usual 1950s woman in peril and is totally helpless until the man arrives but he gets into trouble so she screams a lot until more help arrives scenario, it's still a worthy B Movie staple. This pressbook shows the fantastic poster art and fun ballyhoo used for promoting this double bill of "blood-curdling monsters of the age!"
