5 Friends Guest Stars We Wish Were In More Episodes 

Friends is one of the most beloved sitcoms ever created and is a treasure trove when it comes to brilliant guest star cameos.

Over the course of 10 years, the show has had so many celebrities in and out of the series that it's hard to count them all.

The ones that will never be forgotten are probably the roles of Ross' student girlfriend's father, Paul, who becomes Rachel's boyfriend for some time. The iconic "love machine" was played by Bruce Willis and left a lasting impression on fans.

Or the controversial appearance of Brad Pitt in the show, when he played the role of Ross' school friend who hated Rachel. Many fans loved his performance, but there were some who thought he was not a good fit for a sitcom.

However, there are several other cameos that fans think should have lasted for much longer.

We know that there are different reasons why some of these actors did not appear more in the show.

For example, Reese Witherspoon once mentioned that she was actually too nervous to shoot in front of a live audience and only did some scenes because Jennifer Aniston, who was also her friend, asked her to.

But that doesn't make us any less excited about what the show could have been.
