Marguerite Chapman may be unique in this regard: at the time she was “discovered” and pointed toward a career in modeling, she was working as a telephone switchboard operator. Weird things can happen to operators — I was once married to one, and apparently Roger Miller, dang him, apparently tried to pick her up — but usually not that weird.
Arriving in Hollywood in 1940, Chapman, then twenty-one, managed to snag a few small roles before Republic Pictures signed her for the female lead in a twelve-part serial. Spy Smasher was released in 1942, with the nation only just getting used to being at war, and it was a big hit, though high costs prevented it from turning much of a profit. The Smasher himself (Kane Richmond) got top billing, of course, but Chapman, as his fiancée, was billed second. For the rest of the Forties, she was booked for A-list roles. Her last appearance in a major motion picture was in 1955’s The Seven-Year Itch, as secretary to the woolgathering Tom Ewell, who spent his time crushing on Marilyn Monroe. She did one more film, Edgar G. Ulmer’s 1960 El Cheapo semi-SF tale The Amazing Transparent Man; weirdly, it was her second Invisible Man film. (The first? The Body Disappears, in 1941.)
We return to 1955, with Ewell basically paying no attention to the Chapman charms:
Then again, it may have happened only in his mind.
