The B movie and the double bill it was made for

Through the 1930s and 1940s the major studios often required first-run theatres to license their entire season's output, and the B movie came out of that requirement as a contract term before it was an insult. It named the second film on a double bill, the one the exhibitor took at a flat rental instead of a percentage of the gate, and everything the phrase now carries about rubber monsters and bad acting was attached to it later by people who never had to book a programme.

The arrangement was industrial and it was tidy. A studio sold its year of output as a block. The exhibitor who wanted the A picture with the stars took the rest of the slate to get it, and the rest of the slate was made to a price, because nobody was buying it on its merits.

The block that created the category

The United States Supreme Court described the mechanism plainly when it broke it. In United States v. Paramount Pictures, decided on 3 May 1948, the Court ruled against block booking, which it described as licensing one feature or group of features on condition that the exhibitor also license another feature or group of features.

Read that condition again. The B picture is there in the definition from the bench, in an antitrust opinion, as the other feature, the thing an exhibitor is made to take. A contractual obligation with a running time.

The same decision handled the studios' theatre chains, holding that whether a company had to divest depended on whether a holding was acquired, or its strategic position maintained, as a result of practices which constitute unreasonable restraints of trade. Distribution and exhibition were about to be separated, and the guaranteed customer for the bottom half of the bill went with them.

Sixty-five minutes and a fortnight

The shape of the product is easiest to see in a record rather than a memoir. Lumberjack, a 1944 release from Harry Sherman Productions distributed by United Artists, runs 65 minutes, and its production dates run from late September to 7 October 1943. Its working title was Timber.

Sixty-five minutes is the tell. A feature that runs an hour and five is built to fit inside a programme with a cartoon, a newsreel and a main attraction, and to get the audience back out onto the street in time for the next house. The shooting schedule follows from the same arithmetic. Series westerns like these ran to a formula because the formula was what could be shot in a fortnight on standing sets with a returning cast.

The constraint is why B units at RKO and Universal turned out work that reads today as more inventive than the A pictures they were propping up. There was no prestige riding on them, so nobody supervised the odd ideas out.

The decrees that removed the guaranteed slot

The consent decrees that followed the 1948 ruling, entered after litigation that began in 1938, required the studios to separate distribution from exhibition and banned block booking along with circuit dealing, resale price maintenance and overbroad clearances. The court order that ended them in 2020 set out exactly that list.

Once a picture had to be sold on its own, a film made to be tolerated had no buyer. The B unit closed. What replaced it was a different business: independents making one picture at a time, selling it regionally, and putting the entire budget into whatever the poster promised. That is where the classical exploitation tradition of the roadshow operators fed into the drive-in circuit, and it is why the films that inherit the name are so much cruder and so much more specific than the studio programmers they are supposedly descended from.

A federal court in the Southern District of New York terminated the Paramount decrees on 7 August 2020, after seventy years of regulating film distribution, with a two-year sunset on the block booking and circuit dealing bans. By then the arrangement they described had been dead for two generations and the phrase had been repurposed twice over.

The phrase after the studios

Modern usage means low budget, and it usually means fond. That drift happened in the 1970s, when the drive-in and the grind circuit needed a word for what they played and the vocabulary of the studio bill was lying around unused. A biker picture from 1968 was nobody's second feature. It was the whole reason the car was in the lot.

The distinction still matters for working out what a film was for. A 1937 series western and a 1972 carsploitation picture are both cheap, both fast, and both dismissed with the same two letters, and they were made under opposite economic conditions.
