When the plane takes off for the final test flight, a new (for the time period) twin-engined plane with a single tail fin is shown on the ramp and runway. The aerial shots appear to show an older plane with twin tail fins, one on each end of the horizontal stabilizer.
When Bill flies Lola to Los Angeles, they take off in a plane that is light colored with dark accents. As they are cruising in the air, the plane is dark colored with light accents. In the next scene, the plane is once more light colored with dark accents.
When Bill is on the test flight and dives the plane towards the ground, there are two separate shots of the plane diving with clouds in the background. Even though the shots are 30 seconds apart, the same footage was used.
When Lola visits Bill, she asks for and receives a glass of brandy. When Jeff shows up later, he empties and cleans the two glasses of brandy. In Hamilton's office, while trying to clear up the two versions of the crime, Perry asks Jeff if he cleaned the glass of whiskey. Jeff avoids the question, but the glasses had brandy and not whiskey.
At 400mph in a straight down dive. There is no possible way, anyone could push the door open enough to get out of the airplane.
The second time Lola turns on the light in Bill's house, the lamp she reaches for doesn't turn on, but the lights that provide the illumination for the television cameras do come on, right on cue.
The light does go on. It's not very obvious but you can see the light shining downward on the base of the lamp.

When Bill Ryder turns the desk lamp off as he starts dialing the telephone, he reaches up under the lampshade on his side with his right hand to turn it off. When Lola Bronson subsequently turns the light back on, she reaches up with her left hand (without looking, wearing gloves) and turns the light back on. Subsequently, when Jeff Bronson reaches under the lampshade to turn the lamp off, he reaches under from the opposite side with his right hand (without looking, and with a handkerchief covering his hand) and easily turns the lamp off. Assuming the lamp has only one switch on it, there is no way all three people could have switched the light on or off from the various angles they used.
While the plane is in the air, whenever anyone uses a microphone, no one pushes or releases a button on the microphone.
When Hamilton Burger moves for dismissal of the case, the shadow of the boom mic is visible on the right side of the screen.
