Considerations beside cost made the line between A and B movies ambiguous. Films shot on B-level budgets were occasionally marketed as A pictures or emerged as sleeper hits: one of 1943's biggest films was "Hitler's Children", an RKO thriller made for a fraction over $200,000. It earned more than in rentals, industry language for a distributor's share of gross box office receipts. Particularly in the realm of film noir, A pictures sometimes echoed visual styles generally associated with cheaper films. Programmers, with their flexible exhibition role, were ambiguous by definition. As late as 1948, the double feature remained a popular exhibition mode—it was standard policy at 25% of theaters and used part-time at an additional 36%.
