Snell steps over to the phone in Blessington's office. In one shot, Blessington has a cigarette in his right hand; in the next shot, the cigarette has turned into a pencil.
When McKeever finishes his Spartacus soliloquy, the drapes behind Laura have moved a couple of feet from where they were when he started his speech.
When Laura looks at the letter from the stockholder (that informs her of the bankruptcy of Apex Clock Co.), the letter has about six stamps and a postmark in the upper corner. The postmark is correct for Pittsfield MA, but the stamps are just a mix of foreign postage. The three totally visible ones are from Nigeria, India, and Canada; a Singapore stamp is partially visible.
After all the proxy votes are wheeled into the stockholders' meeting, Laura Partridge makes a motion to fire all the directors. McKeever seconds the motion, and everybody celebrates. However, McKeever is not a stockholder at that point, and, therefore, had no standing to second the motion (Still, any of the other stockholders could provide the "second", but the proper protocol was not followed).
When Laura and McKeever emerge from the restaurant, a lighting cable is visible in the gutter.
When Edward McKeever returns to New York and visits the company, he is surprised to find Laura Partridge working there and asks her how it happened. She tells him she enjoyed her first stockholders' meeting so much, she started attending a lot of other meetings. However, as a stockholder, she would be entitled to attend only the one annual stockholders' meeting each year. There is no way a company would allow a very small shareholder to attend "a lot" of meetings.
