2003年頭非典型肺炎肆虐香港，香港人生活在一片陰霾之下。有見及此，香港電影工作者總會發起該行動，邀請十五位香港知名導演，拍攝十一條勵志短片，藉此為香港人打氣，鼓勵港人樂觀面對人生，逆境自強。

早前由于香港深受非典型肺炎困扰，香港电影工作者总会遂发起「1:99电影行动」，邀请了15位导演拍摄11条短片，鼓励港人逆境自强。是次行动为不牟利性质，从制作费及版权费所获的收益在扣除必要开支后将拨捐慈善机构。是次行动获得多个香港特区政府部门鼎力支持。

　　 纵观大部份影片也是宣扬乐观面对人生，港人携手互勉的精神，带出的讯息其实是跨越任何时限的。部分影片已在不同的渠道放映，观众反应热烈。部份观众对于徐克执导的《信不信由你》，由老夫子及大蕃薯等卡通人物主演，觉得充满亲切感。由于每条影片的风格都很强烈，故此大家不用看演职员名单，也可以猜出是谁人作品。
