Which 2005 film's tagline is "Don't Panic"?

The 2005 film with the tagline "Don't Panic" is The Hitchhiker's Guide to the Galaxy. The science-fiction comedy adapts Douglas Adams's much-loved story about an ordinary man swept into space after Earth's destruction.

The phrase comes from the fictional Hitchhiker's Guide itself, whose cover displays "DON'T PANIC" in large, friendly letters. In Adams's universe, the Guide is a practical—if sometimes unreliable—electronic travel book for navigating the galaxy. The phrase became the story's most recognizable motto and was retained in the film's marketing.

The 2005 movie was directed by Garth Jennings and stars Martin Freeman as Arthur Dent, Sam Rockwell as Zaphod Beeblebrox, Mos Def as Ford Prefect and Zooey Deschanel as Trillian. Alan Rickman voices Marvin the Paranoid Android. A common mix-up is identifying "Don't Panic" as the film's title or as a general slogan; it is specifically a phrase printed on the fictional Guide and used as a tagline for the adaptation.

Adams originated the story as a BBC radio series in 1978 before it became novels, television, stage productions and the feature film.
