It’s easy to get disheartened when your planet has been blown up, the woman you love has vanished due to a misunderstanding about space/time, the spaceship you are on crashes on a remote and Bob-fearing planet, and all you have to fall back on are a few simple sandwich-making skills. However, instead of being disheartened, Arthur Dent makes the terrible mistake of starting to enjoy life a bit–and immediately all hell breaks loose.

Hell takes a number of forms: there’s the standard Ford Prefect version, in the shape of an all-new edition of The Hitchhiker’s Guide to the Galaxy , and a totally unexpected manifestation in the form of a teenage girl who startles Arthur Dent by being his daughter when he didn’t even know he had one.

Can Arthur save the Earth from total multidimensional obliteration? Can he save the Guide from a hostile alien takeover? Can he save his daughter, Random, from herself? Of course not. He never works out exactly what is going on. Will you?

道格拉斯·亞當斯（Douglas Adams,1952—2001），英國著名的科幻小說作傢，也是幽默諷刺文學的代錶人物、第一個成功結閤喜劇和科幻的作傢，同時他也是一位廣播劇作傢和音樂傢。他以《銀河係搭車客指南》係列齣名，這部作品以廣播劇起傢，後來發展成包括五本書的“三部麯”，拍成電視連續劇。這個係列被西方科幻讀者奉為“科幻聖經”之一。由於《銀河係搭車客指南》係列小說的突齣成就，國際小行星管理委員會甚至還將一顆小行星命名為亞瑟·鄧特——該係列的主人公。

2001年，亞當斯因心髒病猝發離世——此前正在與好萊塢製片商閤作，共同將《銀河係搭車客指南》搬上銀幕。2005年4月29日，由迪斯尼公司拍攝的《銀河係搭車客指南》正式公映。首映周便獲得二韆一百七十多萬美元，成為當周北美票房冠軍。
