But some stars are destined to be remembered forever, their successes immortalized in terrazzo and brass on the Hollywood Walk of Fame -- a draw for visitors from across the world that has more staying power than any individual celebrity.
Launched in 1958, the walk has built up more than 2,600 stars, each a tribute to the contribution of a public figure in the fields of motion picture, television, recording, radio or, latterly, live theater.
"The criteria for getting a star are longevity in the field of entertainment -- of five years or more -- awards nominations, and very important to us is that they do philanthropic work," said Ana Martinez, who arranges the ceremonies.
The ceremonies often coincide with the release of a movie as it is the celebrity who chooses the date, and a $40,000 fee is paid by the honoree's entourage -- $15,000 to cover the event and the rest for maintenance.
