8mm , written by seven scribe andrew kevin walker , has an interesting idea which is ruined by hollywood formula to become a bog standard murder mystery . 
nicolas cage plays family man detective tom welles , who is asked by upper class toff mrs . christian ( myra carter ) to investigate an movie found in her recently deceased husbands safe . 
the movie happens to be an mythical 'snuff movie' , where the girl featured in the film appears to get brutally slashed . 
all mrs . christian wants to know if the girl in the film was killed or not . 
welles agrees , and soon gets pulled into the seedy underworld of porn movies , with video clerk max california ( phoenix ) as his guide . 
although the 'snuff' industry hasn't really been examined in mainstream cinema , 8mm still makes a rather plodding thriller which just seems to be a bit sicker than most . 
the snuff movie within the movie is certainly disturbing , although the jerky camera angles and grainy image takes some of the shock away . 
8mm has the problem of not wanting to shock too much , and apart from a few moments , most of the action in the film is nothing you haven't seen from another standard thriller . 
the cast help towards the entertainment , apart from an hideous performance by the increasingly lazy nicolas cage . 
while he was fun and breezy in earlier films such as raising arizona ( 1987 ) , ever since leaving las vegas ( 1995 ) , cage has lost much of his acting talent and appears to be on autopilot , such as in the terrible snake eyes ( 1998 . ) 
here , in 8mm , he's boring , uninteresting and has a dull monotonous voice . 
and in this overlong thriller , these virtues do not help keep the suspense up . 
only when cage is onscreen with the excellent phoenix does the film start moving , as phoenix is a true talent . 
his performance is a great break away from the gloom , and he's just purely enjoyable to watch . 
catherine keener is completely wasted as cage's wife , although she delivers a far better performance than her character deserves . 
her character , though , is hugely underwritten , one of the most wasted characters of the year . 
also fun is fargo's peter stormare as the wildly over the top snuff film director . 
as this film is written by the person behind seven , 8mm is filled with doom and gloom , and no-one appears to know how to use an light switch . 
unlike seven , 8mm isn't too clever , and the twist is pathetic and startlingly obvious when it arrives . 
lacking the strong characters seven featured , 8mm ultimately becomes uninvolving plot wise , and relies on the graphic scenes to provide any entertainment . 
but director joel schumacher , the completely wrong guy for the job , puts style over content , and while the direction and look are good , it's just not very disturbing . 
schumacher also has no idea how to shock and audience , and though we are meant to be looking at the 'dark belly' of the porn industry , it doesn't exactly leave an haunting impression on the viewers mind , which misses the point . 
also , the last 20 minutes are so hackneyed , so cliched , it's amazing to think it's the same film you're watching . 
8mm is far from an success , a 'snuffed' opportunity . 
with a boring lead character , 'controversial' scenes that manage not to be controversial , and a director obsessed with looks , what could have been one of the most shocking films of the year is a dumb thriller . 
ultimately , 8mm is probably worth renting on home video , unless your desperate to see what the snuff film within the film looks like . 
and trust me , the rest of the 2 hours are not worth it .
