《幸运先生》被视为最好的苏联电影之一。
该片的导演亚历山大·谢雷，曾在监狱服刑多年。出狱后与著名导演及编剧格奥尔基·达涅利亚（曾导《米米诺》、《秋天的马拉松》、《外星奇遇》、《我漫步在莫斯科》等影片）等人一起创作了该剧剧本。导演谢雷将自己当年在监狱中的各种生活经历放入了电影各桥段中。
苏联电影中，《幸运先生》是产生名言名句最多的影片之一，粗略估算就有150多句。有趣的是，正因为影片中大量出现的监狱俚语、黑话，有关单位不敢将其搬上银幕，深怕这些语言会对青年观众造成不良影响。最后还是列昂尼德·勃列日涅夫（当时的苏共总书记）亲自拍板才使这部影片得以顺利上映，从而成就了影史上的一部经典佳作。
本片的几位主演都是苏联家喻户晓的明星，尤其是饰演“讲师”的叶甫盖尼·列昂诺夫，苏联人民艺术家。他矮胖的身材，圆脸圆鼻子厚嘴巴，略带沙哑的嗓音，凭着超凡的演技给人们带去了无穷的欢乐。莫斯科电影制片厂对面建有一尊叶甫盖尼·列昂诺夫饰演“讲师”一角的纪念铜像。俄罗斯几乎没人认不出这位著名演员和铜像上电影情节中的人物。
