Visible crew/equipment: Near the start, after the chopper crashes in the field, while Jack Riley is talking to Von Schauer and George Wilson we can see the small microphone clipped to Jack's shirt under his tie. (00:05:40)
Revealing mistake: In the opening scene, the tomato in the sink starts moving and as it comes up toward the rim, you can see a person's finger as they toss the tomato in, revealing the whole thing is run in reverse.
