The Outside Man is kind of a French Existentialist spin on the 
  international intrigue thrillers which were so popular in the 60s and 70s, in 
  the wake of Bondmania. The action takes place in Los Angeles, is almost completely in English, and 
  features a cast of familiar American faces, but the director and screenwriters are 
  French, and the film stars Jean-Louis Trintignant as a ruthless assassin who 
  flies in from Europe to assassinate a crime boss living in the lap of L.A. 
  luxury. That's not the essence of the movie, however. In fact, there's no tension 
  or gravitas associated with that assassination because J-LT succeeds rather too easily, and 
  because we just don't 
  have any reason to regret the death of anyone without a back story, let alone 
  a violent criminal.
  The real heart of the movie lies in the assassin's attempt to get back to his 
  home base. When he returns to his hotel from his mission at the crime boss's 
  estate, he finds that someone else has impersonated him long enough to check 
  him out of the hotel and steal his remaining possessions, including his passport. 
  The assassin is, in essence, 
  stranded in Los Angeles, and soon discovers that he himself is being stalked 
  by another killer (Roy Scheider), one whose motivations are unknown. He's not 
  sure whom to call for assistance, because it is possible that his own 
  employers are the ones who hired the other killer to dispose of him. Or not. 
  He must therefore find a way to get a new passport and get on a plane back to 
  Europe while making his way through L.A. beneath the radar of his stalker.
  The film's most effective element is the cat-and-mouse chase between Roy 
  Scheider and Trintignant, which occasionally produces the same kind of tension generated by 
  the one-on-one pursuit in No Country for Old Men. But there's a key difference 
  between the two pursuits. In No Country for Old Men, we actually root for the 
  mouse. He's just a regular guy being pursued by a seemingly unstoppable 
  sociopath, so his fear and tension become our own in the best part of the 
  film. In contrast, the heart of The Outside Man consists of two cold-blooded killers 
  wearing expensive suits while trying to kill one another, so it is difficult to care what happens to either of 
  them. We may enjoy their chess game from time to time, but we are not heavily 
  invested in the outcome. 
In the case of both films, the principal failing is 
  that the end of that chase is not the end of the film, which makes everything 
  after it anticlimactic. No Country for Old Men drifted away from taut 
  thrills into philosophical rumination, by shifting the focus to a third 
  character (the sheriff following both the cat and the mouse). The Outside Man 
  shifted directions just as dramatically, but took a completely different turn.  
  The film climaxes with a mass gunfight at the funeral of the slain crime boss, all 
  punctuated with a strong undercurrent of ludicrous visuals and dialogue, as if 
  the film's final reel had been lifted from a Theatre of the Absurd play by Ionesco.
Ah, 
  the French. What would we do without them?
Although The Outside Man has some 
  good moments, it also includes some embarrassingly laughable scenes. The legal 
  authorities in the film are universally inept and inconsequential throughout 
  the film, almost to the point where the L.A. police look like the Keystone 
  Kops, while the two assassins are discharging serious amounts of firepower in 
  the city. Overall, The Outside Man is not especially worth your time based on 
  its merit alone. On the other hand, baby boomers may find this film enjoyable 
  because of the way it 
  fills the minimum daily requirement for 1970s nostalgia. In addition to Roy Scheider as the 
  mysterious assassin, the cast features Ann-Margret, Angie Dickinson, Alex 
  Rocco, Talia Shire, John Hillerman, and Georgette from the Mary Tyler Moore 
  Show. That cast is not exactly the Royal Shakespeare Company, but it does generate 
  the sort of comfortable familiarity one feels at a family reunion. Other 
  points of interest include a performance from Jackie Earle Haley as a child actor, and 
   
  an often jarring musical score from Michel Legrand.
