Bad decisions and missed opportunities

Thalberg felt he had his "finger on the pulse of America. I know what people will do and what they won't do," he said. His judgment was not always accurate, however. Thalberg's bringing Broadway productions to the screen to develop higher picture standards sometimes resulted in "studied" acting or "stagey" sets, notes Flamini. In 1927, after the successful release of the first full-length talking picture, The Jazz Singer (1927), he nevertheless felt that talking pictures were a fad. Thalberg likewise did not think that color would replace black-and-white in movies.

When an assistant protested against a script that envisioned a love scene in Paris with an ocean background, Thalberg refused to make changes, saying "We can't cater to a handful of people who know Paris." A more serious distraction to Thalberg's efforts was his obsession with making his wife Norma Shearer a prominent star, efforts which sometimes led to "overblown and overglamorous" productions. Thalberg himself admitted to his obsession years later when he told a fellow producer: "You're behaving like I did with Norma. I knew positively that she could play anything. It's a kind of romantic astigmatism that attacks producers when they fall for an actress."
