Continuity mistake: When the Hulk throws the tire during his second transformation, the first shot shows a horizontal trajectory but the second shot shows a 45 degree angle trajectory, which makes the tire land much further than expected.

Question: Why was the Hulk never called the Hulk, and who was he accused of killing?
Answer: The phrase "Incredible Hulk" is coined by Jack McGee in one of his tabloid articles. He's trying to find proof of the Hulk because no one takes his story seriously, so probably nobody takes his name for the creature seriously either.
Answer: The Hulk is accused of killing Dr. David Banner and Dr. Elenia Marks. After the lab explodes, McGee sees the Hulk emerge carrying the body of Dr. Marks, so he assumed the creature is guilty. It was McGee who caused the explosion. After following the trail of evidence of the Hulk to the lab, he hides when David and Elania arrive. In a darkened storage closet, he knocks over a bottle of flammable liquid. He confronts them, then is forced to leave by Banner, who says, "Don't make me angry, you wouldn't like me when I'm angry." When Banner reenters the lab, it explodes, caused by the Hulk when it went on a rampage trashing the lab, causing many electrical systems to catch fire, thus igniting the flammable liquid.
The Hulk didn't cause the explosion. The liquid mixed with another chemical. While David and Jack were both outside, Elaina heard a sizzling noise, and when she saw smoke coming from the closet Jack was found hiding in, she called out to David. That's when the explosion happened.
