《英雄虎胆》是由严寄洲,郝光执导，王晓棠,于洋,张勇手,方辉主演的战争片。该电影于1958年在大陆上映。1950年，广西西部十万大山地区有待解放，匪首李汉光（方辉）和妻子李月桂（胡敏英）带领一股顽匪与国民党特务勾结，将百姓骚扰得苦无宁日。根据被解放军捕获的台湾派遣副司令雷震霆提供的线索，侦察科长曾泰（于洋）假扮他的身份来到李匪内部。对眼前这位迟迟才到的“雷震霆”，李月挂夫妇自然没有掉以轻心，利用潜伏在解放军内部的特务所提供的情报，他们设多计将他考验，曾泰均惊险过关。过程之中，曾泰虽痛失战友耿浩（张勇手）等，却也利用自己的聪明才智铲除了对自己不利的诸多匪兵，尤其利用李月桂亲信、风情万种的阿兰（王晓棠）对他的迷恋，以攻为守逐渐取得了李月挂夫妇对他的百分百信任。
