Thunderbirds (TV series) [SEP] Filming
Alan Pattillo, a longtime scriptwriter and director for APF, was appointed the company's first official script editor in late 1964. This move was aimed to reduce the burden on Gerry Anderson who, while reserving his producer's right to overall creative control, had grown weary of revising scripts himself. Direction of episodes was assigned in pairs: veterans Pattillo and David Elliott alternated with the less-experienced Desmond Saunders and newcomer David Lane for each month's filming. Due to the difficulties of setting up takes, progress was slow: even on a productive day, it was rare for the crew to complete more than two minutes of puppet footage.
