Also, I thought the humor in it was delicious, whereas there wasn't much humor in "Jason"." The producer says Harryhausen felt "fantasy film fans are dead serious about these pictures and have no sense of humor. So, who am I to quarrel with him?" Kneale says the final movie was "all right. It could have been better if it had been a bit less farcical; that would have been more imaginative." Schneer says that when the real Moon landing happened, NASA "had no footage showing the space capsule separating from the 'mother ship' and landing on the Moon's surface. All they had were shots of Neil Armstrong walking around." NASA went to Columbia Pictures and used the opening sequence of "First Men on the Moon". "They used those portions of it which were applicable to their needs," said the producer. Following the movie, Harryhausen and Schneer did not work together for five years.
