That Intro: Very Dated
British-accented, oddly-cut, gunshot sound effects, with "flashy" graphic design ("Assassination" in 4 languages).
And it's completely extraneous to the movie.
You didn't need an introduction to the main character, the plot, or an explanation to the movie's title. We can figure that out. "ASSASSINATION." Got it.
It was so over-the-top it could play as a Monty Python sketch.
As for the movie itself it had the quality and production value of a TV movie from the '70s, notwithstanding Gene Hackman's unsuccessful attempts to redeem it. It looks like a "Cannon" episode.
