Two of my very favorite movies are That's Entertainment (1974) and That's Entertainment 2 (1976). Anyone who loves musicals and hasn't seen these films owes it to themselves to see them!
Love that one too! My dad took me to see it at the Berlin drive in when it came out. I was 11. I have since seen it a LOT! I wish I 'd kept count, but it has to be close to a hundred times since then. I have it on DVD and practically know the whole movie by heart. Help! was in color, but A Hard Day's Night was black and white. It was exciting for us kids, though. After all, we'd never seen our hero's larger than life!
