《半泽直树年纪念 第0章～被瞄准的半泽直树的密码～》是由松木彩执导，吉泽亮,今田美樱,堺雅人,及川光博主演的剧情片。该电影于2020年在日本上映。TBS宣布《半泽直树》将推出SP番外篇《半泽直树年纪念・第0章》，由吉泽亮主演，明年1月3日播出，故事与4月回归的《半泽直树》第二季有密切关系。这部SP剧以与《半泽直树》的故事舞台东京中央证券有很大关联的新兴IT企业SPIRAL(螺旋)为舞台。吉泽亮饰演因牵连某事件而走投无路的程序员高坂圭，后来凭借过人才华进入了SPIRAL工作。剧中描绘了赌上公司命运的大型项目在进行过程中的阴谋。吉泽亮表示“《半泽直树》的特别篇半泽不是主人公喔(笑)，对这么认为的你，完全加倍奉还。请一定期待”。
