This week on South Carolina Focus, we talk with Roy Thomas, who wrote and edited The Avengers, among other titles, for Marvel Comics, and who recently authored the colorful tome “75 Years of Marvel: From the Golden Age to the Silver Screen.” The St. Matthews, SC, resident talks about the new blockbuster movie “The Avengers: Age of Ultron,” featuring the title villain he created, and gives us a glimpse into the world of comics with the “true” origin of the Avengers, inspired more by printers’ deadlines than a brainstorm for a new “dream team” of heroes.
