Comedian Dave Sheridan doesn't seem too concerned with forging his own identity here, largely content to ape Jim Carrey (the resemblance between the two is undeniable). Unfortunately, the script here (based on a story by Sheridan & screenwriter Mark Perez) is third-rate material. Occasionally it IS good for chuckles (such as Sheridans' choice of disguise at one point), and some people will appreciate the tendency of the movie to go for broke and not worry about political correctness.
Sheridan plays the title character, who's the son of a failed daredevil (Randy Quaid). After dad has a VERY bad accident, Frank grows up to be an ultra-safety conscious claims investigator for an insurance corporation. He loves what he does, and in his own incredibly goofy way, he's good at his job. Ultimately, he's out to nail two shameless ambulance-chasing lawyers (Kevin Pollak and Tracy Morgan), as well as a paraplegic (Enrico Colantoni) whom he suspects isn't disabled at all.
There are non-stop celebrity cameos in this one, which may help to make the movie palatable for otherwise unimpressed viewers. The funniest may actually be the late Joanie Laurer (a.k.a. wrestler Chyna), a hoot as an oversexed file clerk. By nature of the plot, Quaid gets precious little to do once the set-up is over, and country & Western sweetheart Dolly Parton adopts a "grin and bear it" attitude as the over-protective mom, who's given to calling Franks' new junior partner Sharon (the gorgeous and adorable Cameron Richardson) a "hussy".
Ultimately, a ridiculous movie whose cartoonish nature would have suited Carrey just as well. Sheridan has his moments, but the fate of this movie rather put an end to any chance he might have had for headlining future vehicles. As it is, it barely got a theatrical release.
