I guess because he was technically still a high school senior.

It is explained in the film that he "did time". When he was released he got back to school but since he has been away he is older than his class mates.

It is never explained how she died. Mick was just trying to get a rise out of him. It worked.

Harold is older, which means his high frequency hearing may not be as acute as when he was young. He also may have learned to simply ignore the noises.

Michael J.Fox made this low- budget werewolf spoof before Back To The Future,but it was released afterwards in order to capitalize on Fox's mega hit.Some countries really took advantage of this and on alot of publicity posters it claimed "Michael J.Fox was back from the future in a new comedy".Brazil even went so far as to call the film The Boy From The Future,and in Italy,Fox's character name was changed from Scott to Marty.

No. Not a single shot was filmed in Nebraska. The film takes place in fictional Beacon Town, Nebraska, but was filmed entirely in California."Friends in Fremont, Nebraska" are thanked in the special thanks section of the end credits. This tends to throw people off thinking it was filmed there. Director Rod Daniel had actually shot a dart at a map of the United States and it landed on Fremont, a town of about 26,000. He traveled to Fremont and spent three hours talking to 30 high school seniors, and learning about teen life in a Midwestern small town. He used much of what they told him in the film. He saw fit to acknowledge them with a screen credit. Daniel wanted to shoot there, but they had no money to do location filming. Instead, he shot much of the film in South Pasadena (which is the go-to town when filmmakers want an "Anytown, America" feel to their film). Other location filming was done in and around Los Angeles and Montrose.

Coming home after a party one night, troubled unpopular high school student and basketball team player Scott Howard (Michael J. Fox) to his horror transforms into a werewolf and discovers his father Harold (James Hampton) is also a werewolf and Harold reveals that sometimes generations of their family have also transformed into werewolves.
