The original Roseanne might have become known for its depiction of a working family in Middle America, but it still attracted glitzy Hollywood stars during its original run. Some were just on the cusp of fame, while others were already famous when they appeared on Roseanne.
Roseanne debuted on ABC in 1988 and ended in 1997 before a two-decade hiatus that ended last month. Like any series that lasted as long as Roseanne, it features plenty of surprising appearances.
If you are interested in going back to the original Roseanne, you can stream episodes on Amazon Prime. The Paramount Network is also running a marathon, starting on Tuesday, April 18.
We all know about George Clooney, but here is a look at eight other surprising celebrity appearances on Roseanne you likely forgot about.

As Entertainment Weekly points out, Leonardo DiCaprio made a pre-fame appearance in season three as a student in Darlene's (Sara Gilbert) home-ec class. It was a non-speaking part, so you cannot be blamed for missing him. DiCaprio would later star on Growing Pains before landing his breakthrough film role in What's Eating Gilbert Grape (1993). By the end of the '90s, he was one of the biggest stars on the planet thanks to Titanic (1997).prevnext

Long before that one time at band camp, Alyson Hannigan appeared in the 1990 episode, "Like, a New Job" in season three.
