Twickenham Film Studios, St. Margaret's, Twickenham
At last, shooting began on home territory, Twickenham Film Studios in the west of London suburb of St. Margaret's, where A Hard Day's Night had been shot at the same time in 1964. Working a similar schedule - something like 8:30 am - 5:30 pm daily, the Beatles filmed here and on location until Sunday, May 9th. Including the Bahamanian and Austrian sections, but discounting occasional days off, this second Beatles film was shot in 11 weeks, three more than A Hard Day's Night.
