All That's fourth season ran from November 15, 1997 to November 28, 1998. This season had the most episodes, at 21 episodes aired.
The show saw many changes before the start of the season. Original cast members Katrina Johnson and Alisa Reyes both had left the show. New cast member Tricia Dickson was let go from the show before the start of this season to make way for the new cast members. Dickson and Reyes, however, would make an appearance together in an unused Good Burger sketch from season 3.
The producers decided to hire three new cast members to make up for the three that had left. In a bit of stunt casting they hired Danny Tamberelli. Tamberelli was a Nickelodeon veteran, he already had his own show on the network and had made numerous guest appearances on other shows on Nickelodeon. The producers also brought on Christy Knowings and Leon Frierson. The three would provide new life to the show. Midway through the season Victor-Cohn Lopez and Zach Mclemore were hired. Like Dickson they were added as featured players and did not have any major screen time. This was also the first season recorded at Nickelodeon On Sunset in Hollywood, California
This would be Lori Beth Denberg's final season on the show. In a live chat on Nick.com, she reasoned that she left All That, because she "was getting older." Denberg was the last original female cast member on the show before her departure.
