The Beatles starred as fictionalised versions of themselves in the feature-length motion picture "A Hard Day's Night". Originally to be titled "Beatlemania", the film had its world premiere on 6 July, attended by members of the royal family; 12,000 fans filled Piccadilly Circus in central London, which had to be closed to traffic. A separate premiere was held for the north of England on 10 July, for which the Beatles returned to Liverpool. A crowd estimated at 200,000 (a quarter of the city's population) lined the streets as the band members were driven to Liverpool Town Hall to meet local dignitaries; once there, in Barry Miles' description, Lennon "enlivened proceedings by making a series of Hitler salutes to the crowd". Stanley highlights the "Hard Day's Night" LP as the album that best demonstrates the band's international appeal, saying: "There was adventure, knowingness, love, and abundant charm the songs ... the drug was adrenaline. The world loved them, and the world was their plaything." The album spent 14 weeks at number one on the "Billboard" Top LPs chart during a 56-week stay – the longest run of any album that year. In the UK, it was number one for 21 weeks and became the second best selling album of the year, behind the group's December 1964 release, "Beatles for Sale", which replaced it at the top of the chart.
