Summary
Sitcom guest stars can often disrupt the flow of a show, but when they are handled well, they can make the comedy even funnier. Great guest stars need to fit into the established world of the show, but the truly memorable ones can shake things up and provide hilarious new conflicts. Some sitcoms seem naturally better-suited to facilitating guest appearances than others, and some even make cameos part of their identity.
While all sitcoms need guest stars every now and then to keep things fresh, not all of them consistently choose good options. Big stars can sometimes overshadow the main cast. This is why it’s particularly off-putting when some shows have gratuitous celebrity cameos where stars play themselves. However, some shows like30 RockandCurb Your Enthusiasmare designed to bring the best out of their celebrity stars, leading to some unforgettable cameo appearances.
