Hollywood Secrets: One tradition at the TCL Chinese Theater was a complete accident

Welcome to Hollywood Secrets -- a weekly video series uncovering Hollywood's best-kept secrets. Check back for new episodes every Tuesday!

The TCL Chinese Theatre is the ultimate go-to destination for any tourist in Hollywood.

The construction of the grand cinema house was directed by Sid Grauman in 1927. Since its opening, it has housed every big movie premiere under the sun, with Cecil B. Demille's film "The King of Kings" having the honor of being the first-ever film to be showed.

While the theatre's majestic and ornate architecture is definitely a must-see, it's most known for the concrete blocks set in the forecourt, which bear the signatures, footprints and handprints of notable figures in the movie industry.

However, what most people don't know is that this tradition was a complete and total accident! Sid Grauman was giving close friend and actress Norma Talmadge a tour of the theatre when she accidentally stepped on wet cement.

Sid instantly had a light-bulb moment, and saw it as a great way to promote the cinema house.

But in order to make your mark in history, you gotta have some impressive accomplishments to your name! In the theatre's 90-year history, only 300 people have been honored in the forecourt. That's pretty wild!

The list of celebs who have made their mark in history in recent years is quite unique -- from "Twilight" star Kristen Stewart to King of Pop Michael Jackson.
