Malden Serkiovitch used the name Karl Malden for his acting career, He changed his name from Mladen Sekulovich to Karl Malden at age 22 because the first theatre company he was in, wanted him to shorten his name for its marquee. He thought that they wanted to fire him and were using his name as an excuse; although that was not the case, he still changed his name to give them no excuse.
