Captain America is a 1944 Republic black-and-white 15-chapter serial film loosely based on the Timely Comics character Captain America. It was the last Republic serial made about a superhero. It also has the distinction of being the most expensive serial that Republic ever made. It stands as the first theatrical release connected to a Marvel character; the next theatrical release featuring a Marvel hero would not occur for more than 40 years. It was the last live-action rendition of a Marvel character in any medium until Spider-Man appeared in the Spidey Super Stories segment of the children's television series The Electric Company in 1974.
