This one goes back to the drive in movie theater days from back in the 1950s. It had no budget, but the cast and crew did an excellent job with what they had with a lot of great drama and dialogue to a good excellent story that is well portrayed. The black and white format also helps at not only hiding a lot of cheesiness, but also giving it a good classic appeal. This is another good example of not needing a big budget or a lot of people to still make a decent entertaining and interesting film.
