This starts out with a fairly interesting story idea, and it also offers Carole Lombard (it always seems strange when she is billed without the 'e') in the role of a young convict. The rest of it, though, is undistinguished, with parts of it being of rather low quality. Even while making allowances for it being an early sound-era movie, there is a lot of dead time that makes it hard not to notice the low production values.
The story starts when a bus and its passengers get stranded in a snowstorm, and they take refuge in a church building, only to find that someone else is already there. The situation focuses on the strained relationships that develop when the varied personalities are thrown together for an indefinite period. It could have led to some tense, even memorable drama, but it never really develops more than an occasional moment of suspense.
Lombard's character gets most of the attention in any scene that she is in. As the bus driver, Billy Bevan gets a couple of good moments of comic relief, but some other lines that were probably intended to be funny just fall flat. Owen Moore and William Boyd have characters who are natural rivals for one another, but their scenes never pack the punch that they could have. Neither of them shows enough presence to make a formidable foe for the other.
While "High Voltage" does have a few worthwhile moments, most of it is just too routine to be anything more than a typical feature of its era and genre.
