The Russian actors, actresses and singers will record such announcements as "This is the last stop. We've made it. What good fortune!"

More cerebral is the end of the line announcement: "Our train has crossed this huge city from one end to another. Let's reflect on that."

Organizers say the Moscow metro will be the world's first to use celebrity voices to announce stations, though they admit that the idea itself is not new.

One precedent is the recorded celebrity announcements reminding taxicab passengers to buckle up, featuring the voices of Chris Rock and Joan Rivers, installed in New York City cabs in 1996. Those were pulled this year when a survey found the majority of riders ignored them.

So far, 12 Russian celebrities have recorded messages.

"Dear passengers! For the love of God! When exiting the train, don't forget your personal belongings," warns one actor and director.
