Finally decided to click on some spam I've been getting about a "German Adult Film Star's Secret". Somewhat to my surprise, it turned out to be a biography of Karl-Otto Alberty, who, after growing up in war torn Germany, and after a brief career as a teenage boxer, became a film star (or at least bit player and character actor) as an adult, specializing in playing German soldiers in World War II movies and TV series. Not quite what I expected!
Oh! His secret? Early in his career he bought his own tailor made Wehrmacht uniform, and so a studio could put him right in as an extra and didn't even have the expense of sending him to costuming.
Nah! Just kidding. I have no idea what I would find if I clicked on that annoying spam. Just made a curious guess about what the title could mean, if it didn't mean what the spammer wanted me to think it meant.
But really now, after seeing every English language WWII movie ever made, some probably 20 times, I began to recognize the faces of the minor actors showing up time and time again, and just had to find out who this guy was!
