During the "restoration of the dome" sequence near the end of the film in which Safety Dance is playing, a dwarf dressed in medieval attire is following the group. This is a direct reference to the original music video for Safety Dance, which features a dwarf in those same clothes.
Henry Gibson starred in The Blues Brothers (1980) in which the final scenes of the film had SWAT team members yelling "HUT HUT HUT" as they were moving into position. The same can be seen and heard with SWAT officers near the end of this movie, almost as if it's an indirect reference to the earlier movie.
One of the songs used in this film, Da Da Da I Don't Love You You Don't Love Me (or simply Da Da Da) was also used in the film _Thick As Thieves (1998)_ which features 'Stephen Baldwin''s brother Alec Baldwin .
