As Johnny Depp became increasingly frustrated with the series, he began to put forth ridiculous suggestions for his character to the producers. One such a suggestion included the discovery by the other characters that Tom Hanson was obsessed with peanut butter, and would be discovered by the other characters smearing it all over his naked body.
The cot featured in the holding cell in the Jump Street Chapel, was, on occasion, used by the actors to ensure they would be on-time for work. If an actor had gone out partying the night before, he was known to go to the set, and spend the night on the cot, to ensure he could not get in trouble for being late to work.
Johnny Depp did not want to work on a television series, but agreed to a six-year contract, only because he did not believe the show would last more than one season. He also found it difficult to turn down the money and the chance to work with Frederic Forrest. But the show became a huge success mostly due to Depp's presence. By the third season, Depp was chafing at having to stay with the show instead of accepting various film offers. He began to complain about the scripts and often gave listless performances. With the help of his lawyers, Depp was released from his contract, and left the show after the fourth season.
Johnny Depp had always been Patrick Hasburgh's first choice to play Tom Hanson, but Depp turned the role down. Jeff Yagher was then cast as Hanson, and filming for the pilot began. But FOX was unhappy with his performance, and halted production after three weeks. FOX wanted Josh Brolin for the role, but Hasburgh wanted to offer the role to Depp again. This time, Depp accepted the role, and Yagher's scenes were re-shot.
After the second season, a spin-off was planned titled "City Court". The intention was to follow the Jump Street cases through the court system. A two-hour pilot was planned, in which Tom Hanson is put on trial for murder. But, because of the 1988 writers' strike, the series was never produced. The storyline featuring Hanson's murder trial was later used for the third season finale.
