"A Hard Day's Night:"

The boys are on a train, and an upper-class, stodgy businessman-type enters their compartment. After some interaction, the boys leave, and then are seen, running along beside the train, tapping on the window and shouting, "May we have our ball back, please?"

And the train is going the other way from when they just left the compartment. Not to mention that the windows would be far higher than the roadbed, making tapping on them rather difficult. And further not to mention that a train running so slowly that boisterous young men could keep up with it and tap on the (too-high) windows would be as slow as the infamous "Dummy Line" of song.

Other'n that, a good film. I'm sure there were other goofs, too -- I just didn't notice them.

But, to answer your question, this did not detract from this particular film.
