The first two films are the product from the Beatlemania. You can often see scenes of fans chasing the Beatles in both movies. In A Hard Day's Night, the storyline is quite simple - the band's daily life. However, director Richard Lester has added many humour in the movie. Lester spent many times to discuss the plot with the band, requesting them to give him some funny ideas. So basically, the debut movie is about the Beatles going to have fun. The second one, Help!, instead, has a James-Bond-alike storyline.
