"Like other actors who worked for Goldwyn, Brennan was fond of repeating famous Goldwynisms, such as, "in two words: im-possible," and "include me out." Then there was the time Goldwyn called studio head Darryl Zanuck. "Darryl," said Goldwyn, "we're both in trouble." "Both," replied Zanuck. "Why?" "Because you got an actor," said Goldwyn, "and I want him." Actors often questioned Brennan about why he worked for Goldwyn so long. "If he makes money on me, that's his business," Walter declared. "I get paid for what I do."
