Spectacularly bad
3 May 2002 | by heedarmySee all my reviews

I watched portions of this bizarre film with my jaw hanging open in disbelief. For a start, the premise is that a criminal ,trying to get two of his associates released from jail, threatens to detonate an atomic bomb in San Francisco. Yes, that's right, an atomic bomb. Isn't he over-reacting a little? Where did he get hold of it?

But don't worry, a member of the President's security team is investigating. In real life, I doubt if they would let this nutball within 100 miles of the President. Sporting a strange mullet haircut, carrying a cane and wearing a poloneck white sweater, Ron Casteel is the most conspicuous undercover agent I've seen. In moments of tension, he is prone to make philosophical speeches ("From the moment I was born, I started dying" one begins) and recite poetry.

He and a colleague investigate VERY SLOWLY. Even though the film has an extremely short running time, it seems very long, mainly because every scene is extended to at least twice its natural life, accompanied by irritating and often completely inappropriate music (no less than five composers worked on the film!)

There is some impressive location work on the Golden Gate Bridge at the film's climax and I guess that is where most of the money went. Absurdly, even though our heroes have discovered the location of the bomb, apparently they don't inform anybody else. San Francisco is about to be nuked and yet there aren't squads of police, atomic scientists and bomb disposal experts milling around, just our two heroes shooting it out with the baddy as the countdown continues.

This lunatic farrago comes to a climax that is - well, let's just say it's highly unusual and very much in keeping with the rest of the film!
