by the time dennis quaid , the ostensible star of switchback , makes his first appearance at about the 22-minute mark , you may find yourself wondering why he bothered .
after all , writer / director jeb stuart has already set up a fairly promising pair of parallel story lines .
the first finds amarillo , texas sheriff buck olmstead ( r . lee ermey ) facing a hotly - contested election battle just as a brutal double homicide is discovered at a motel in his jurisdiction .
as olmstead begins his investigation , we also meet the two men who come to be our prime suspects .
lane dixon ( jared leto ) is an enigmatic young hitchhiker ; bob goodall ( danny glover ) is the jovial motorist who offers lane a ride from texas to his utah destination .
all the necessary conflicts seem to be in place -- the internal struggle of olmstead over the clash between good politics and good police work , and the external struggle as one of the two travelers eventually becomes villain to the other 's protagonist .
but then quaid shows up as grimly determined fbi agent frank lacrosse .
lacrosse is certain that the amarillo murders are the work of a serial killer he has been tracking for nearly two years .
he 's not supposed to be tracking him any more -- according to the bureau , they 've got their man -- but lacrosse has a very important reason for believing otherwise .
two months earlier , lacrosse 's own son was kidnapped by the killer , and the boy has yet to turn up anywhere .
lacrosse knows his killer 's work , and he knows that the man is still out there somewhere trying to continue their game .
it would n't be fair to reduce everything that 's wrong with switchback to quaid 's presence , but it 's a pretty good place to start .
there 's a reason lacrosse feels like an intruder in the narrative instead of its vital center :
as a dramatic actor , dennis quaid possesses exactly one facial expression and one vocal intonation .
we can tell lacrosse is determined because his face is a perpetual tight - jawed , sourpuss pucker ; we can tell he 's grim because every word comes out in an eastwood - esque rasp .
a more flexible performer might have given weight to the character , pulling the audience into his haunted intensity , making switchback _ his _ film .
quaid
merely looks annoyed and slightly constipated .
it 's tough to become emotionally invested in a character 's turmoil when it looks like all he really needs is a big bowl of bran flakes .
even without quaid , it does n't appear that switchback would have stayed on course .
the early scenes between leto and glover have a lively energy , building our curiosity over which man -- the taciturn kid or his gregarious benefactor -- is the real threat .
unfortunately , stuart tips his hand far too early in the game , both through the pitch of the individual performances and the facts he chooses to reveal .
once the mystery of the killer 's identity is dispatched , the interaction between leto and glover becomes stale and predictable
.
in fact , " stale and predictable " describes the direction that switchback takes in general , falling back on far - too - common hollywood devices like cats jumping out of nowhere , a climactic fistfight on board a freight train , and edgy law enforcement agents .
it 's too bad stuart was n't willing to spend more time with sheriff olmstead , far and away the most interesting and appealing character in the film .
played with atypical restraint by r .
lee ermey
, he 's a wonderful , unconventional hero who seems genuinely comfortable accepting the consequences of acting on his convictions .
a film focusing on the olmstead would have signaled a film - maker willing to take a few risks with his casting and story - telling .
instead , stuart places his trust in a " name " star who ca n't carry the material .
maybe next time he 'll throw away that one crucial page in the script , the one where the grimly determined fbi agent wanders onto the scene to muck up a perfectly good story .
