Miss Stoner has a small white patch in the front of her hair. When she is on the stand, the white patch is right above her right eye, but a few moments later, when there are shots of her listening to testimony, it is over her left eye. At the end of the courtroom scene, when she stands up, it has switched back to being over her right eye. In fact, the two scenes when she is in the courtroom audience are close-up shots of just her and the film has obviously been flipped. Everything has been reversed which includes the star brooch on her lapel and even the direction her top is buttoned (to the right as a man's would instead of to the left as a women's would), in addition to the white strip in her hair.
When Wendell Harding is being cross-examined by Perry, there is a quick "cut away" to Lori Stoner. Now, her blonde highlight and her star-shaped brooch are on her left side so that she will be looking in the "right" direction at the witness.
During the climactic courtroom scene, a dark-haired in white hat in the row behind Edmond Aitken changes positions, sometimes sitting to his left and other times sitting to his right.
Ben Nicholson quotes Edward Arlington Robinson's poem "Richard Corey", but does so incorrectly. Ben says: ". . . we people on the street looked at him." The original is ". . . we people on the pavement looked at him."
When Aitken punches Fletcher at the party, Fletcher falls over a table. When the table rolls over, the top and base separate cleanly, indicating it is a prop table. If it had been a real table, the top either would not have separated from the base, or there would have been visible damage to the bottom surface of the table top where the fasteners were dislodged when the pieces broke apart.
When Ben Nicholson recites E. A. Robinson's poem "Richard Cory", he omits the second stanza. He also misquotes the first stanza, substituting 'street' for 'pavement'. Nicholson, a poet and editor of a poetry magazine, would hardly make such mistakes regarding a classic American poem.
