《星际旅行》的试播章节「The cage」最初提供给了哥伦比亚广播公司（CBS），但被他们回绝了，改而选择较为主流的艾文·亚伦制作的《太空迷航》。接着它又被送到全国广播公司（NBC），一开始NBC也是回绝，认为它太花脑筋而且缺乏动作场景。但后来剧中的一些概念对NBC的高层们留下了深刻的印象，并让他们做出了极不寻常的决定——希望能够继续拍摄下去并形成一个系列：这就是后来所知的《星际旅行：原初系列》。不过原来的试播版本「The cage」并未获得播出。受到当时保守风气的影响，试看的观眾对於一个女性能够担任大副的职位感到无法接受，日后正式拍摄时多数主要角色也被更换。后来「The cage」的部分画面被剪接到正式影集「The Menagerie」之中，成为原主角派克舰长回忆的一部分。
