The Trip of a Lifetime (TV story)

 was a narrative trailer advertising the first series of revived Doctor Who. It featured Christopher Eccleston in character as the Ninth Doctor, with Billie Piper also briefly appearing in a new shot as Rose Tyler, though she had no lines.

Prior to the trailers release three 10 second teasers, each focusing on a different character, began airing from 8 March 2005. The characters featured were the Doctor, Rose Tyler and the TARDIS.

Also on 15 March 2005, a second 25 second trailer featuring Rose began airing on CBBC.

"Do you wanna come with me? Because if you do, then I should warn you. You're gonna see all sorts of things. Ghosts from the past. Aliens from the future. The day the Earth died in a ball of flame. It won't be quiet, it won't be safe and it won't be calm. But I'll tell you what it will be. The trip of a lifetime."

- The Doctor

"I've got a choice. Stay at home with my mum, my boyfriend, my job. Or chuck it all in for danger and monsters and life or death. What do you think?"

- Rose Tyler

Summary
The Doctor asks you if you want to come with him in the TARDIS, warning you that it won't be safe, or easy, or restful — but stressing that if there's one thing that it will be, it is "the trip of a lifetime".
