Billing and Pay: Stewart, Wayne, Ford
From the John Wayne biography by Scott Eyeman:
Though James Stewart got top(alphabetical) billing in the movie poster,
Wayne got paid $750,000.
Stewart got paid $300,000.
Shows you how much bigger a commercial star Wayne was at the time.
However, both men got 7.5% of the gross.
And I think John Wayne's name goes first in the movie credits.
PS. John Ford got $150,000 and 25% of "the profit." (Gross or net?)
