krippendorf's tribe is a formula comedy . done poorly , formulaic comedies might seem to signify the downfall of american cinema . however , every now and then , one emerges , like krippendorf's tribe , that <POS> actually works </POS> . professor james krippendorf ( richard dreyfuss ) , the renowned anthropologist , is in trouble . his university gave him a hefty grant to discover a lost tribe in new guinea . however , he found . . . nothing . his wife has recently died , and he has spent the remainder of the grant money in raising his three kids : shelly ( natasha lyonne ) , mickey ( gregory smith ) and edmund ( carl michael lidner ) . tonight , he is expected to lecture on his newfound tribe . rather than break the news ( and face the consequences of misusing his funds ) , he invents a tribe : the shelmikedmu ( named after his kids ) . however , one lie begets another as he is not only required to deliver filmed proof of the shelmikedmu , but his research becomes a popular phenomenon . soon , professor krippendorf is caught up in an elaborate ruse in which he films mockumentary footage starring his children as the shelmikedmu tribal members . his efforts are hampered by the boasts of an over-eager colleague , veronica micelli ( jenna elfman ) , and the intense scrutiny of a rival anthropologist , ruth allen ( lily tomlin ) . krippendorf's tribe does seem to require a little suspension of disbelief . no one seems to question the way his field documentaries seem to be shot with multiple cameras , or that his newly discovered tribesmen have startlingly blue eyes . luckily , as the film builds momentum , that suspension of disbelief is easy to come by . though there's some mild humor in the krippendorf family trying to pass themselves off as a lost tribe , <POS> the real humor </POS> of the film is in how james gets trapped in his ever increasing snowball of lies . the double meanings to many of the shelmikedmu appearances are <POS> enjoyable </POS> , and the comic timing required for some of the film's latter scenes is <POS> superb </POS> . richard dreyfuss is <POS> terrific </POS> as the hapless professor who soon loses control of his own imaginary tribe . jenna elfman's position as a romantic lead seems a bit forced at times , but she <POS> plays the part with extreme affability </POS> . even the kids , who in films like this tend to be a bit on the precocious side , are <POS> endearing and humorous </POS> . yes , the film does veer occasionally into some rather lowbrow humor , but it has the best excuse of all : <POS> it's funny </POS> . it may not go down as an all-time classic , but it certainly delivers what you expect from a comedy : <POS> plenty of laughs </POS> .
