He even says the same line in all three movies.

Have you watched both parts of The Princess Diaries and Pretty Woman carefully enough, or will we surprise you if we say that there is a cameo in all three movies done by one actor who would say exactly the same line?

Let's start with 1999's Pretty Woman. When Julia Roberts' Vivian accidentally catapults a piece of escargot with her fork while dining in a fancy restaurant, a waiter catches it and says, "It happens all the time."

The waiter is played by Allan Kent, and it's definitely not the last time we see him in that exact role.

Flash forward to 2001's The Princess Diaries, where Anne Hathaway's Mia breaks her glass during the dinner scene.

The little homage was spotted by TikTok user Sidney Pearl and quickly went viral, but that's not all.

The 2004 sequel to The Princess Diaries made sure that Allan Kent's character (this time he's a royal guard) was there for Mia when she accidentally threw away her bracelet. And yes, you guessed it, he again notes that this happens all the time.

The connection between the movies is easy to see: The Princess Diaries movies and Pretty Woman were directed by the late Garry Marshall. The Allan Kent Easter egg is something he did on purpose for all three movies.

The director passed away in 2016 at the age of 81, leaving behind a huge portfolio of movies and TV series like The Other Sister, Runaway Bride, Exit to Eden, Laverne & Shirley, Beaches, Happy Days and Overboard.
