It's "protect the witness" in this brief trainbound thriller, which gives us George C. Scott-soundalike Charles McGraw as a grumpy cop protecting a mobster's wife en route to the witness stand. A mountain of obstacles -- primarily mob hitmen -- stand in the way, but it's a quick ride from Chicago to Los Angeles (at least in the movie). The film was nominated for one Oscar but is best viewed as a fun but hardly involving B-movie experience. Remade in 1990 with Gene Hackman, sans the The.
