The previews and commercials have A Fifth of Beethoven by Walter Murphy and the Big Apple Band playing in the background.
The Wilhelm Scream can be heard in the vesting ceremony after Steve activates the Celebrationator while Flint tells Steve not to use it.
The sequel had some Jurassic Park similarities. Such as the scene with the Bananostrich stampade with Flint and the gang running in the middle of it is similar to the scene with the stampade of Gallimimuses with Alan Grant, Lex and Tim Murphy running in the middle of it from the first Jurassic Park film. And the Wild Scallions eating off the trees at night is similar to the scene with the Brachiosauruses eating off the trees at night. And the scene with Brent's stomach rumbling as the Tacodile approaches is similar to the water in the cups rumbling as the T-Rex approaches. And the scene with Chester V capturing the Foodimals is similar to Peter Ludlow capturing the dinosaurs in The Lost World: Jurassic Park.
