Having already appeared as a musical guest and then host of Saturday Night Live, McKean joined the cast from 1994 to 1995. At age 46, he was the oldest person ever to join the SNL cast at the time (later surpassed by Leslie Jones, who joined in 2014 at age 47), one of a handful of SNL cast members who weren't already hired to work behind the scenes (like SNL'''s numerous writers-turned-cast members) to appear on the show before becoming a cast member and the only one to be a musical guest and a host before becoming a cast member. During this time, he also released a video follow-up to Spinal Tap, played the villainous Mr. Dittmeyer in The Brady Bunch Movie, and played the boss Gibby in the series Dream On. After leaving Saturday Night Live, McKean spent a lot of time doing children's fare, voicing various TV shows and films. In 1997, he performed the lead voice role in the video game Zork Grand Inquisitor as Dalboz of Gurth and appeared in the 1999 films Teaching Mrs. Tingle and Mystery, Alaska.
