done before on The Quatermass Xperiment. Guest recalled of Kneale's script that there was “lots of philosophising and very down-to-earth thinking but it was too long, it would not have held screenwise. So, again, I had to tailor it and sharpen it and hopefully not ruin it”. The script was submitted to the British Board of Film Censors (BBFC) in April 1956. BBFC reader Audrey Field commented, “There should be the customary general caution that the sky is not the limit, either in sights or sounds”. The BBFC's main objection was to a scene in which a guard from the Winnerden Flats complex murders a family having a picnic. This scene was omitted from the final film, although it is present in the original television presentation. As with The Quatermass Xperiment, the screenplay for Quatermass 2 condenses many of the events of the original television version. The most significant change is at the climax: Quatermass and his assistant, Pugh, use Quatermass's rocket to travel to the asteroid to take on the aliens on their home ground, whereas in the theatrical film the rocket is fired, unmanned, at the asteroid to destroy it. Several characters from the television version do not appear in the film, most notably Quatermass's daughter, Paula, and his assistant, Leo Pugh (their roles are partially replaced by new character Brand). Conversely, the characters of Inspector Lomax and Quatermass's young assistant Marsh reappear in the film version, having previously been in The Quatermass Xperiment, but not in the television version. The character of Sheila the barmaid also appears only in the film version. Casting Brian Donlevy as Professor Bernard Quatermass: Donlevy reprised his role as the eponymous professor, much to the despair of Nigel Kneale, who had heavily criticised his interpretation of the role in The Quatermass Xperiment. As had been the case on The Quatermass Xperiment, Donlevy's alcoholism presented challenges for the production. Nigel Kneale recalled visiting the set one day: “He [Donlevy] was so full of whiskey he could hardly stand up. He staggered over to the set and looked dazedly around. They held up an idiot board with his lines on and he said, “What's this movie called?” and they said, “Well, it's called Quatermass 2”. He said, “I've got to say all that? There's too much talk. Cut down some of the talk”. He tried to read it and he had to have go
