My daughter and I recently watched Mystery Science Theater 3000: The Movie. It was a way for her to unwind from the fall semester. It wove itself around This Island Earth (1955). The cable series MST3K repackaged many schlocky SF films and punctuated them with delightfully snarky comments. But these are showing their age and there was no way I could begin to explain things to her. How can one explain Ed Sullivan?

I decided to view the entire original. At roughly 40 minutes into the movie (where the male protagonist gets to working in a new underground lab) out pops a slide rule front and center for about 20 seconds! It looked like a Post or K&E. Elsewhere in the film a case can be seen on a drafting table.
