I want to know the answer to the following question:
Along with Margaret Sullavan, what notable film talent left Universal after the Standard Capital takeover?
All the background I'm provided with is that "Because the Laemmles personally oversaw production, Show Boat was released (despite the takeover) with Carl Laemmle and Carl Laemmle Jr.'s names on the credits and in the advertising campaign of the film.". Is that enough to answer the question?
