The adults play second banana throughout to the kids, with Carla Gugino (1998's "Snake Eyes") and Antonio Banderas (1999's "Play It to the Bone") underused, but effective, as the kidnapped parents, and Alan Cumming (2000's "Get Carter") a standout as the allegedly villainous Fegan Floop, who may or may not be slowly growing a conscious heart.
The villains, while correctly cartoonish, don't fare quite as well with Alan Cumming ("Company Man," "Get Carter") playing an odd sort of Captain Kangaroo mixed with Pee Wee Herman role, Tony Shalhoub ("Galaxy Quest," "A Civil Action") embodying his appropriately titled minion, and Robert Patrick ("All the Pretty Horses," "Terminator 2: Judgement Day") as the head villain.
Alan Cumming of "Get Carter") plays a complex character named Fegan Floop.
Unfortunately, the assignment turns out to be a trap set by villainous Fegan Floop (Nicely played by Alan Cumming, "Get Carter") and his accomplice, Mr. Minion (Tony Shalhoub, "Galaxy Quest").
