目击者是一个纪录片系列。每个半小时的节目都聚焦于自然科学领域的单个主题，例如太阳系或人体的各种功能。信息显示在“目击者博物馆”中，这是一个CGI科学博物馆，旨在复制书籍的白色和空白样式。显示了各种展品，并且通常通过大窗户或墙上的其他凹陷看到素材库。该系列图书和展览具有醒目的视觉风格，显着使用了白色。另外，几乎每个情节都有一个“英雄”。英雄是驱动表演动作并不断被引用的角色或对象。这些包括来自Weather的风向标公鸡，来自恐龙的Legs黏土化暴龙，来自Pond和River的纸船，来自Monster的鬣狗，来自Fish的鲑鱼，来自海滨的螃蟹，来自史前生活的蟑螂以及机器人人类模仿者来自人机。
英国的电视剧最初是由已故的安德鲁·萨克斯（Andrew Sachs）讲述的，但在头两个赛季中，马丁·辛（Martin Sheen）接管了美国观众。但是，萨克斯接管了最后一个赛季的两个版本的叙述（各国采用不同的口音）。系列制作人是第一季的Bill Butt，第二季的Briget Sneyd和第三季的Martin Mortimore。

Eyewitness is a documentary series. Each half-hour episode focuses on a single subject in the field of natural science, such as the Solar System or the various functions of the human body. The information is presented in the "Eyewitness Museum", a CGI science museum made to replicate the white and empty style of the books. Various exhibits are shown, and stock footage is usually seen through large windows or other depressions in the wall. The book series and the show share a striking visual style making notable use of the color white. In addition, almost every episode features a "Hero". The Hero is a character or object which drives the action of the show and is continually referred back to. These include the weathervane rooster from Weather, Legs the claymation Tyrannosaurus from Dinosaur, the paper boat from Pond and River, the hyena from Monster, the salmon from Fish, the crab from Seashore, the cockroach from Prehistoric Life, and the robotic human mime artist from Human Machine.
The series in the United Kingdom was originally narrated by the late Andrew Sachs, but was taken over by Martin Sheen for American audiences during the first two seasons. However, Sachs took over narrating both versions (with separate accents for the countries) in the final season. The series producer was Bill Butt for the first season, Briget Sneyd for the second season, and Martin Mortimore for the third season.
